Power output ranges from 200W to 1,000W to cover most needs, whether you’re a daily commuter or want a bike for extended off-road adventures.
At the heart of every battery is a premium battery chip for extended performance. Each cell can also be charged over 500 times without compromising the battery’s performance. Even better – you don’t have to drain the battery of its charge before re-charging to extend its life. Every battery delivers over 1,000 charging cycles, or over 5 years of service life.
Bike batteries can be burdensome to carry, especially when they’re heavy and bulky. This one is relatively lightweight, which makes it especially appealing as a backup option. The lowest capacity battery (36V 8AH) weighs just under 4 pounds while the largest 48V 20AH battery weighs 8.37 pounds.
This boxy battery isn’t the most aerodynamic, which could make it a tougher fit on some ebike frames. However, it has a wider range of applications than most other batteries on this list, which are strictly for electric bikes.
How Do I Know Which Battery to Get for My Electric Bike?
Whether you’re buying a backup battery or want to upgrade, you need to get a battery that’s compatible with your ride. You’ll need to stay within the recommended range to avoid potential issues.
Most manufacturers sell lithium-ion batteries, which are popular due to their affordability and low maintenance over time.
According to the University of Washington’s Clean Energy Institute, lithium-ion batteries have a low self-discharge range of 1.5 to 2 percent per month. This low rate means a longer shelf life. They’re also relatively easy to dispose of as they don’t contain cadmium.
As you shop for the best battery for your electric bicycle, you’ll notice several numbers. Some of the most important include watt-hours (Wh), amp-hours (Ah) and volts. Many manufacturers also list the amps, although this isn’t the same as amp-hours.
Watt-hours combine voltage and amp-hours to determine how far you can ride on a single charge. Amp-hour ratings suggest a perceived capacity, or how long the battery can operate over a specific amount of time.
Which Battery Is Best for an eBike?
Every battery comes with its own set of numbers to give you a better idea of how much power, performance and run time you can expect on your rides.
However, these numbers aren’t concrete. Just because a manufacturer suggests a certain range, it doesn’t necessarily mean you should expect those same numbers.
Every bike and rider is different. Realistically, numbers will vary from one rider to the next. Factors such as terrain, bike and rider weight, and even weather conditions can influence how long your battery lasts with each ride. A fat tire electric bicycle, for example, will likely require a larger battery than a more compact step-thru e-bike for commuters.
What Is the Lifespan of an Ebike Battery?
According to BatteryUniversity, the capacity of a lithium-ion battery may deteriorate after just one year. This type of battery might completely fail in just two or three years. However, some lithium-ion packs can last as long as five years.
Some manufacturers include an expected charge cycle for their batteries. For example, you might notice your battery of choice is rated for 500 or 600 cycles. This number will give you a rough idea of how long your battery might last under normal circumstances.
How Much Does an Ebike Battery Cost?
Most replacement batteries cost between 200 to 500. Larger batteries with a higher capacity typically sit at the higher end of the price range.
For example, a 36V 10Ah battery may cost 200 and a 48V 11.6AH can cost over 400. Regardless of the price, you’ll want to make sure that the battery is compatible with your bike.
What Size Is Best for an Ebike Battery?
Just as every bike and rider is unique, so is an e-bike battery. The best size e-bike battery for your ride depends on many factors, including the size and weight of the bike and your typical riding routes.
A smaller battery is faster, efficient and slightly cheaper. But it might not offer the power and performance you actually need for more demanding tasks, such as off-road rides on your electric mountain bike.
Take an entry-level battery, such as a 36V 10Ah battery, and compare it to a beefier 48V 15Ah battery. The 36V battery weighs less but doesn’t have the larger amount of power or riding range as the 48V battery.
While the 36V battery is more practical and economical on lighter folding ebikes, the 48V battery offers more bang for your buck if you’re a larger rider or have a heavier electric bike. This is especially true if you frequently ride up long, steep hills, or transport cargo on your electric beach cruiser bike.
Introduction: DIY E-bike Battery || Assembling 48V Hailong Battery
About: I am an electronics enthusiast. I post frequent updates on my projects at my instagram page @hyper_makes. About hyper_makes »
In this instructables i will add extra insights for my tutotial on how to assemble a Hailong battery(48v) for E-bike battery.
BE SURE TO CHECK OUT THE VIDEO FOR THE ASSEMBLING PROCESS.
And if you want more details you can see my instagram handle @hyper_makes
Step 1: Parts and Supplies
I AM PROVIDING THE LINKS TO THE PARTS AND THINGS I USED WHICH ARE NOT AFFILIATED
18650 Li-ion cells EV grade 3C discharge rate : Local supplier
BMS(13S 60A) : BE SURE TO CHECK THICCNESS BEFORE ORDERING HERE
TOOLS REQUIRED :
Step 2: BE SURE TO CHECK THE THICCNESS OF BMS AND SET SPOT WELDER TO CORRECT MODE
Before you order your BMS(Battery management system) circuit be sure to check its thiccness because there is very little space inside the case.
ALSO CHECK YOUR MOTOR CONTROLLER FOR MAX CURRENT OUTPUT. MINE HAS 45A(MAX) CURRENT RATING SO, THE NEAREST BMS I FOUND HAS 60A(MAX) OUTPUT.
ALSO THE BMS CONNECTING WIRES SHOULD BE SOLDERED FIRST TO THE NICKEL SHEETS BEFORE WELDING THE SHEETS TO CELLS.
SPOT WELDER SHOULD BE SET TO 300 MILLI SECONDS MODE FOR GOOD WELDING JOINT.
Step 3: SEEK AND FOLLOW CORRECT WELDING DIAGRAM
Follow the correct welding diagram given with the battery kit. IF NOT THEN GOOGLE ABOUT YOUR BATTERY CONFIGURATION AND FIND CORRECT DIAGRAM. EXAMPLE IN MY CASE : 13S5P CONNECTION DIAGRAM.
Step 4: MASK THE BATTERY PROPERLY BEFORE ASSEMBLING
Mask the battery properly so that it is safe from any kinds of short circuits and accidental shorts.
IMPROPER MASKING OF BATTERY CAN LEAD TO FIRE ACCIDENTS AND DEAD BATTERY.
Step 5: WIRE ACCORDING TO DIAGRAM PROVIDED WITH KIT OR GOOGLE AND THEN DO THE FINAL ASSEMBLY
Do the wiring according to the diagram provided with kit you bought or google about it.
THE PHOTOS I HAVE PROVIDED ARE JUST COMMON EXAMPLES ON HOW TO DO WIRING AND CONNECTION.PLEASE CHECK IT WITH YOUR BMS AND BATTERY IF YOU ARE GOING TO FOLLOW!
Snugly fit all the wires at the edges of the case so that you can close the lid of the case properly.
Hot glue wires in place for more secure fit.(If necessary)
That’s it. You have assembled your own e-bike battery. Check video if you are stuck somewhere.
STILL IF YOU HAVE ANY KIND OF QUESTIONS, BE SURE TO COMMENT DOWN BELOW. I WILL TRY MY BEST TO HELP YOU OUT. 🙂
Step 6: Update:Do Not Use Switch Provided in Battery Case!
The switch provided in the battery case is rated for AC applications only and can’t handle large currents for DC applications, thus making it a potential bottleneck for the current flow. The switch can burn easily in this high current application when you will use the hub motor at full power.
SO I RECOMMEND NOT TO USE THE SWITCH IN WIRING THE OUTPUT WIRES. IF YOU HAVE ALREADY WIRED THEN YOU CAN SIMPLY SHORT THE THE PINS WITH 12AWG WIRES TO BRIDGE IT.

Hi, Thanks for the tutorial, wondering if you can provide the wiring/connections instructions to battery level indicator display. It will be very helpful if you can also share how we can connect the USB port of the hailong case. I understand we need with step down USB module.Appriciate your response.
for safety and sake of completeness you might want to add a fuse. for a 500w motor a fuse of 20a or 30a would be sufficient. get a (car) fuse and fuse holder. also i would advice to use 12 awg (20a) or 10 awg (30a) cable, i dont see you state wire thickness in the article. thanks for your great guide, it helped me build my pack.
Yes! You are right. A fuse would a very good extra safety feature. Pardon me, i have not mentioned anywhere in the article but i have used 12 awg cable for connections indeed. Glad to hear i could help you.
Hello,First I would like to thank you for the tutorial !I’m surprised that you mention not to use the included ACC ON/OFF switch that comes with the case.I have followed my case supplier instructions that says that to use with we must buy a BMS with pre wired ON/OFF.So the included ACC ON/OFF do not cut the main power but just the BMS electronic ON/OFF.I can understand that in your case if you have note the proper BMS you must avoid to use the switch.Best regards,Marcelo

Replacement Electric Bike Batteries Guide
43 Комментарии и мнения владельцев
A good e-bike battery should last for hundreds of cycles. With average use, this means several years. Eventually, electric bike batteries need to be replaced as their life cycle comes to an end.
You can tell when a battery is nearing the end of its life when it does not provide you with much range. Some high-quality batteries that come on the top e-bikes such as a Bosch battery have a battery management system (BMS) integrated into the battery that actually tells you the current capacity and also how many charge cycles it has gone through.
But no matter what type of battery you have you’ll sooner or later be asking yourself the all-important question: how can I replace my e-bike battery?
Down below Electric Bike Report dives into this question and more in greater detail.
Are E-bike Batteries Interchangeable?
In general, the answer is no – you should only replace a battery with one that comes from the same manufacturer and is of exactly the same spec.
The reason is that the original e-bike or kit manufacturer has the responsibility to ensure that the battery pack, charger, and e-bike all work safely together, and using a ‘non-original’ replacement pack potentially introduces all sorts of uncontrolled risks.
It’s a little more complicated than this in some situations. For example, some Bosch batteries of different capacities are explicitly made to be interchangeable and there will be many instances where an original supplier and/or manufacturer of the e-bike cannot be traced or has gone out of business – in such cases we look at your options below.
As an important side note: you should always, if possible, use a charger that comes from the original manufacturer too. The one that comes with your battery should sync up well and not overload the battery. Pairing your battery with a different charger adds in risk of malfunction during charging.
Let’s first look at the basics of getting a replacement battery for your e-bike, then we will look at some of the major manufacturers of e-bike batteries and some of the main e-bike manufacturers to see which common battery types are still replaceable. Let’s consider the options for replacement in terms of desirability.
Where Should I Go to Get a Replacement E-Bike Battery?
On this last point it may help to note that there are a couple of manufacturing standards for rechargeable lithium-ion batteries used in e-bikes. Although it’s not a legal requirement, it may be that one of the standards is actually marked on the battery itself.
The standards are BS EN 50604‑1 and UN38.3, the latter required for lithium-ion battery transport by air, sea or land. Just because these standards are not marked on a battery doesn’t mean it does not comply with them – but it is a reassuring sign if a battery does bear one or both of these marks.
Note that using a replacement battery that does not come from the original manufacturer (whether a dealer is involved or not) may void the warranty of your electric bike or kit. Check with the e-bike or kit company to understand what their policy is regarding the use of aftermarket replacement batteries.
Replacement Batteries from Original Manufacturers
Bosch E-Bike Batteries
Only Bosch manufactured batteries will be used on any new Bosch e-bike – this has always been the case and so it makes advice on interchangeability a little more straightforward than with the likes of Shimano and Brose who have both allowed the use of third party batteries with their mid-drive motor systems.
There have been four basic designs made by Bosch over the years (good online overview here):
- Rack mounted batteries: PowerPack in 300, 400, and 500 Wh versions which are all interchangeable with each other.
- Down tube mounted batteries: PowerPack in 300, 400, and 500 Wh versions, current versions of which are all interchangeable with each other.
- Frame integrated batteries: PowerTubes in 400, 500, and 625Wh versions, with the 400 and 500 units being interchangeable with each other. The 625Wh may be retrofittable but it needs a compatible frame with a big enough space to house it (400 and 500 units are the same physical dimensions but 625 is bigger). 500 and 625 Wh units are used on the Dual Battery system to give a capacity up to 1250Wh.
- Frame Integrated ‘Smart’ Option batteries: This is a new 750Wh option for 2022 and will be only compatible with 2022 e-bikes that feature the Bosch ‘Smart’ system and will not be compatible with other Bosch e-bikes that are ‘non-Smart’. Similarly, other types of PowerTube batteries (400, 500, and 625Wh versions) will not be compatible with e-bikes featuring Bosch’s ‘Smart’ system.
Some third-party batteries compatible with Bosch systems are available as detailed in the section below.
There are some suppliers of batteries that will fit older models, in some cases dating back to 2011 when the Bosch e-bikes first entered the market, for example, The Holland Bike Shop in Europe sells some batteries compatible with much older Bosch-powered models.
Shimano E-Bike Batteries
Shimano produces its own brand batteries for use on their systems, but you may also find new e-bikes powered by Shimano motor systems with batteries manufactured by their licensed partners Darfon and SMP. These third party batteries are not interchangeable with any Shimano batteries.
Shimano’s current range includes rack-mounted, downtube-mounted and frame-integrated batteries from 418Wh to 630Wh. You can see a brief overview with detailed links to each battery on offer here.
It’s important to note that each battery model has a limited number of specific battery mounts it will work with, so it is important to replace an old battery with one that is compatible with the mount on your e-bike. You can check out detailed compatibility info here and here.
Shimano says that ‘the oldest current battery we have is the BT-E6000 and the corresponding battery mount BM-E6000. These are compatible with all five of our current drive units (DU-EP8/E8000/E7000/E6100/E5000), but not earlier systems. For reference, DU-E8000 is the oldest in that list – it was introduced in 2016.’
Brose E-Bike Batteries
The only battery listed on Brose’s own website is a 630Wh frame-integrated option.
However, Brose systems are widely used by other manufacturers who also spec own-brand or third-party batteries. These include the likes of the widely respected battery manufacturer BMZ and well-known brands like Scott and BULLS.
For example, Specialized’s ‘full power’ range use Brose-based mid drives and a range of their own brand frame-integrated batteries. Although information on interchangeability is scarce, a Specialized FAQ page, in response to the question ‘Can I increase range by using the 604Wh aftermarket battery in any Turbo Vado/Como?’ says yes, all Vado batteries are cross-compatible as long as you are running the latest firmware (by implication so are Como and Turbo full power batteries are cross-compatible too).
The above appears only to address compatibility on current Specialized models and battery availability for older models appears a bit more complex with lots of debate online over the matter.
The fact that the latest Specialized e-bike batteries contain a Bluetooth chip to communicate with the latest Mission Control App certainly suggest both backward compatibility and availability of third party batteries will be very limited. Current e-bike batteries available from Specialized can be found here.
Yamaha E-Bike Batteries
Yamaha has integrated, rack-mounted and frame-mounted options ranging between 400Wh and 600Wh but information on backward compatibility is rather hard to find. Their systems appear on Haibike models and in the US on their own brand models too.
Giant use Yamaha motor systems but apparently have their own brand of battery – the EnergyPak range. The standard EnergyPak comes in rack-mounted and frame-integrated options whilst the Smart Compact variant allows for faster charging.
Finally, there is the Giant EnergyPak Plus, for use with the Smart Compact – a range extender style battery that fits onto the frame and effectively increases the capacity of the main Plus battery.
Giant’s Service web page states that there are EnergyPaks with 300, 360, 400, 500 and 625Wh capacities and also states ‘Giant EnergyPaks are interchangeable’.
Fazua E-Bike Batteries
This lightweight German-made system uses a frame-integrated 250Wh design and there have been two types of battery, Battery 250 and Battery 250X, the latter having the ability to be switched on and off remotely.
The latest Fazua Evation 250X battery is compatible with all Fazua electric bikes from 2019-22.
GRIN and Cytronex E-bike Kit Batteries
Canada’s GRIN is a true expert in producing a wide variety of e-bike kits. Whilst they do several designs of batteries, one of their best options from a replaceability point of view is their own brand LiGo batteries.
LiGo batteries are very unusual in being modular so that you can easily connect together as many as you like to increase or decrease battery capacity at will. They are particularly suitable for lightweight and folding bikes (I use them on a GRIN Brompton kit) and also for those who want to air travel with e-bikes as the individual battery units are only 98Wh and so are generally allowed on passenger aircraft (disconnect them from each other for travel and reconnect them on landing to make a useful e-bike battery).
The design has been around for several years and is backward compatible.
The UK’s Cytronex produces both European and US spec lightweight kits which use a unique own-design of ‘bottle battery’.
Cytronex says all their lithium bottles are compatible forwards and backward from the first version in 2017. They have different firmware for the new Bluetooth variant but both this and the non-Bluetooth version allow you to use the new 2-way – 5 level Boost Button or the previous one-way 3 level button.
In fact, if you have old and new kits on two bikes you can switch the bottle between both and it will recognize the two different button types automatically.
E-bike Manufacturers Own Brand Batteries
There are hundreds of e-bike manufacturers in the more budget space so it’s way beyond the scope of this guide to cover the options for each one; rather we’ll take a look at a couple of the market leaders.
Rad Power Bikes E-Bike Batteries
Rad Power Bikes first started producing e-bikes for the North American market in 2015 and now claims to be the US market leader. Their website lists several replacement batteries and their current lineup of bikes uses one of two battery designs.
There is the External Battery Pack (with the option for the smaller pack specific to the RadMission) which is compatible with all 2018 and newer model ebikes except the RadRover 6 Plus and RadCity 5 Plus, which use the Semi-Integrated Battery Pack.
Rad Power Bikes does offer legacy options for bikes older than that 2018 ‘cutoff’ and although some of these legacy batteries are currently out of stock Rad says they have plans to restock them.
The battery packs are consistent across their main sales areas of Canada, US and Europe.
The Rad Power website has a great filter system so you can track down the compatibility of what batteries are in stock against all current and previous models, right back to the original 2015 RadRover. All e-bike manufacturers’ websites should provide this service!
Pedego E-Bike Batteries
A longstanding US manufacturer with a clear set of battery specs for current models here. However, there doesn’t appear to be any info about legacy batteries or backward compatibility.
Interestingly, and it seems uniquely amongst the mainstream manufacturers, Pedego have recently introduced a serviceable battery (pictured above) – designed to be easily maintained at the local Pedego store. It features a rear light, brake light and indicators to boot.
Batteries for Out-Dated Motor Systems
There are a number of older motor and battery systems that are either not used or little used these days but there are still some suppliers out there who may be able to help out and if you are in this position a bit of internet research might just turn something up. Let’s take a look at a couple of examples.
BionX E-Bike Batteries
BionX operated between 1998 and 2018 and were once one of the leading e-bike system manufacturers in North America, with the likes of Trek and Kalkhoff using their systems.
There are still limited stocks of spare parts available here and there, including batteries, for example on this Ohm webpage.
Heinzmann E-Bike Batteries
German company Heinzmann had a great reputation for quality and produced the now obsolete Classic system and the newer Direct Power system. At various times both were available as kits or fitted to off-the-peg e-bikes.
In the UK Electric Vehicle Solutions are the main stockist of complete Direct Power kits and of spare parts for the Classic system.
What About Non-removable Frame Integrated Batteries?
A relatively small number of e-bike batteries are incorporated into the frame and not designed to be removed by the rider – they must be charged on the bike. Whilst perhaps inconvenient for some, the system has the benefit of a sleeker and simpler design and keeps the battery cells well-protected.
The Ebikemotion X35 system is one example of the most common lightweight systems out there to feature a frame-enclosed battery.
When it comes to replacing these batteries, to be clear, our official advice is that this is a job for the dealer, or expert shops to do only.
DIY in this area can get tricky in a hurry. Looking into service options to replace batteries in an integrated system is something to consider before purchasing the bike.
Third-Party Replacement E-Bike Batteries
For some older batteries – or even some current ones – there may be manufacturers other than the so-called OEMs (original equipment manufacturers) who made the original batteries. These third-party companies are not recognized by the original e-bike manufacturers so if possible it is always best to go back to your dealer or the manufacturer directly to source an original battery.
However, third-party batteries may be a solution where no original batteries appear to be available.
There are a growing number of companies that provide third-party batteries and here we take a look at a couple of the bigger operations.
Please note that on e-bikes that are still in their warranty period, replacing the battery with one from a third-party manufacturer will most likely void the warranty.
FTH Power has a good amount of experience in the electronics business and has diagnostics and assembly capabilities. They look to have good stocks of popular far eastern battery brands such as Reention (used by the likes of Juiced and Surface 604) and Hailong. They also have this handy battery/model finder to see if they have batteries for your particular model of e-bike.
Third-party battery provision (and recelling services) appear to be bigger business in mainland northern Europe than in the U.S. It makes sense, this is where e-bikes have been around much longer and where the average value of e-bikes is higher. The need to keep older bikes going longer is greater. For example, Heskon is a major supplier of replacement batteries to dealers and Fiets Accu Revisie is the part of Heskon that sells direct to customers.
The UK’s Electric Transport Shop network offers battery diagnosis (refundable against a replacement battery or recell if required). The ETS says they also have stocks of Battery Management System chips that can be used on certain packs, usually on older e-bikes.
The ETS also says ‘There are so many shapes of e-bike batteries now that we cannot guarantee that we have cell packs to fit them all and it is usually cheaper to buy a factory-built replacement than to hand-build a replacement pack in the UK so we usually recommend buying a battery from the original supplier if the diagnosis proves that’s what is needed. If their supplier is no longer available to supply a replacement pack in this instance we will help people find a suitable replacement or as a last resort we will offer to wire in an alternative pack which may be in a different position on the bike.’
What Should I Do With My Old E-bike Battery?
If at all possible the ideal solution is to take it back to the dealer you bought it from who will send it on for recycling.
In the US the industry is in the midst of setting up its own recycling scheme. It was organized by People for Bikes and will be directly coordinated under the auspices of Call2Recycle. There will be a network of battery drop-off locations from the nation’s roughly 3,000 independent bike shops. Manufacturers and retailers can sign up here.
The batteries will be sent on to ‘processing partners’, four of which are domestic and two of which are foreign—one in South Korea and one in Belgium.
The consortium brands are funding the recycling service, which will be free to riders; of course, consumers will still have to pay for replacement batteries. There are also plans for a consumer-direct mail-in recycling option in the summer – EBR will keep you posted on its development.
There are already such ready-made recycling networks in mainland Europe and the UK is just beginning to establish such a network.
This guide to replacement electric bike batteries hopefully covered the basics of what is out there for you. It’s certainly just the tip of the iceberg though.

Customs policies vary greatly among countries. Therefore, we cannot, and will not, offer advice about taxes in your country. We report the amount of the sale on the Customs form. Please do not ask us to claim less than the actual purchase amount. It is the customers responsibility to know the legality of the electric bike ordered in their country. Do not order items that are illegal to import into your country. Laws are different in every country and we cannot keep up with them all.

Important Freight LTL Shipment
How to Handle Damages, Exceptions or Discrepancies at time of Product Delivery (Carton packaging appears to have some damage such as ripped, holes, large dents, open carton, or items are missing):
- Carton damage requires visual inspection of contents of the unit.
- UrbanBikesDirect recommends IMMEDIATE inspection, with driver present, to verify damage. If contents are damaged, indicate damage on carrier’s paperwork and notify UrbanBikesDirect immediately.
- IMPORTANT: If contents cannot be inspected immediately, notation on carrier’s paperwork must state: “Carton damage, subject to inspection” and list type of damage.
- Contents must be inspected within 48 hours of arrival and actual damage reported to the carrier
Carton packaging has excessive damage with the exposed electric bike:
- Refuse shipment
- Sign carrier paperwork: “Carton damaged and refused”
