Common E-bike Battery Problems and How to Fix Them

There’s nothing worse than having to spend hundreds or thousands on an eBike only to have problems with its battery. Don’t get me wrong; e-bike batteries are built to last. but they’re still prone to failure if they aren’t adequately taken care of during their lifetime.

What happens if your battery fails?

Well, in this article, I’ve covered some most common eBike battery problems and how to fix them. So, if you’d like to know more. keep scrolling!

Ebike Battery Problems

When it comes to eBike troubleshooting, there are a couple of things that might be causing your battery problems, including:

  • eBike battery pack swelling
  • eBike battery not charging
  • eBike battery not running for very long
  • eBike battery pack not holding a charge
  • eBike not turning on
  • eBike not speeding up

Don’t worry, though. I’ll walk you through each one here!

eBike Battery Pack Swelling

If your eBike battery pack is swelling up, well, you likely have a pretty serious problem with one. or more. of the lithium-ion cells.

Some electric bike models use flat pack cells. and these are known to swell if they suffer some damage. On the other hand, the 18650 lithium-ion cells are far more resistant to swelling and, in turn, more reliable.

If you notice that your eBike’s battery pack has a bulge in it, be sure you turn off the power and carefully remove the battery from your eBike. It’s a good idea to recycle the battery; most cities have a place where you can do this.

Now, some eBike battery packs are positioned inside the bike’s frame. That makes it somewhat harder to notice if you have a swollen battery pack.

The only way to check if the battery is swollen is to drop the lower plate and take out the battery pack. Note that you’ll have to disconnect some cables before you do this.

eBike Battery Not Charging

If your battery isn’t charging, start by checking the following:

  • Is the power turned on at the outlet?
  • Is the charger working and outputting over 36 Volts?
  • Is the battery hot?
  • Is the battery charger port full of dirt?
  • Has the battery been left discharged for several months?
  • Has the fuse blown in either the eBike battery pack or the charger?

eBike Battery Not Running For Very Long

Lithium-ion batteries generally have a life of 700 charge cycles. They usually tend to lose full charge capacity over this mark.

That is entirely normal. and will, unfortunately, only get worse as time goes on.

Still, if you’re charging your bike every few days, you should be able to get many years out of your electric bike before you begin to notice the capacity of your battery is starting to degrade.

If you notice your eBike battery isn’t running as long as it used to, check the following:

  • Is the battery pack being charged to 100%?
  • Do you have a dragging of a disc brake?
  • Is the terrain uphill?
  • Are you assisting your battery by peddling?
  • Are your eBike’s wheel bearings freely spinning?
  • Do you have a short circuit in the battery, wiring, or motor?

Any of the scenarios mentioned above could lead to your battery discharging rather quickly.

eBike Battery Pack Not Holding A Charge

Lithium-ion batteries are good at holding a charge. However, like any other type of battery, they will slowly discharge over time.

If your eBike hasn’t been charged for a more extended period, it would be a good idea to give it a top-up. and see how it goes.

If you notice that you’re charging your battery, but it still discharges quickly without being used, you might have a short circuit somewhere or a faulty battery at your hands.

Here’s a quick test that can detect the problem:

Remove the battery pack from your eBike and charge it up on a bench. Once it’s fully charged, test the battery by leaving it off the bike.

If it holds a charge, the issue will be your electric bike. most likely a short circuit in the bike’s wiring or the motor. However, if it doesn’t hold the charge, your lithium-ion cell is faulty.

How Do I Know If My Bike’s Battery Is Charged?

Your battery charger will probably feature a LED light indicator that changes states depending on the bike’s battery level. It’ll go from red to green when the battery is fully charged in most cases.

However, in some chargers, the LED light will turn off completely when the battery is charged.

Either way, the point remains the same. you’ll have a way to track the progress while charging the battery.

Remember not to leave the battery pack on the charger longer than 24 hours, though.

Lithium-ion batteries don’t prefer being left on the charger. In the short term, this won’t hurt. but after a while, the battery’s capacity will go down.

You’ll also have an indicator of the battery’s current level on the battery pack itself or the speed controller. Some will use a 0-100% range, while others have a series of LED lights, depending on the model.

eBike Not Turning On

Let’s start with the obvious solution:

If your e-bike isn’t turning on, be sure to check if the main switch is in the “On” position.

Next, check the fuse for the battery pack. This fuse is usually located on the side and could blow up because of short circuits, vibrations, over-current, or old age.

If the fuse is in good condition and the battery pack is fully charged, check if the speed controller is in good condition, as well. The speed controller is the component that sends signals to turn on the battery pack.

These speed controllers could malfunction if damaged. either by dropping your bike or allowing water to get into them.

Hold the bike’s “On” button for about 10 seconds to force the speed controller to turn on. Some speed controllers are turned on by pressing the “M” button. Again, it depends on the e-bike model you have.

Be sure to check that your battery pack has at least two bars of power. An extremely low battery power level can lead to your electric bike not turning on, by the way.

Another thing to check here is that the electrical cables are correctly connected. Sometimes, the dirt roads can dislodge the cable connections; this is often the case with mountain electric bikes.

Water can find its way into these connections, too. Pull them apart and ensure the connection is tight.

eBike Not Speeding Up

There are numerous reasons why your electric bike isn’t speeding up.

often than not, the feedback magnets. positioned on the pedal crank or the rear wheel hub. for the proximity switch get dirty. Clean them with a rag, and you should be good to go.

This common eBike battery issue is often wrongly diagnosed.

Most quality electric bikes feature a switch on the back and front brakes to stop the drive motor. In some cases, these switches can get stuck. leading to their failure. Activate both brake levers a couple of times to try and free up the switch.

To check the limit switch, though, you might have to remove the whole rear or front brake lever. That’s another reason why you should avoid leaving your eBike out in the rain.

Also, while it might sound obvious, be sure to check if you’re in the proper mode. for example, pedal-assist, throttle-only, or pedal-only. I’ve sometimes found myself in the wrong mode, and I couldn’t figure out why my eBike isn’t speeding up.

There is typically a minimum speed that will activate the drive motor. That is just a safety feature. and it’s usually around 1.8 mph.

What Speed Are eBikes Limited To?

eBikes are limited to 25 km/h. or 15.5 mph. to conform to the majority of road rules around the globe. Once the motor reaches this speed limit, it will stop providing power further.

Of course, you can still pedal faster than 25 km/h, but you won’t get any assistance from the main motor.

Once the speed controller recognizes that you’re under 25 km/h, the battery management system will again supply power to the main motor. That is a standard component on most electric bikes. and, again, its role is to ensure that you conform to road rules.

Is 250Watts Enough For An eBike?

In most standard cases of use, 250W is more than enough power for you to ride your eBike on asphalt or dirt roads casually. A 250W drive motor is usually limited to 15 mph and can handle up to 240 pounds in rider weight.

If that doesn’t sound impressive, remember that you can always assist the main drive motor by pedaling.

You can always upgrade your bike with a Bafang conversion kit, though!

Conclusion

We can agree that e-bikes have come a long way since their first appearance. Granted, battery problems can occasionally happen, but most can be solved easily and quickly.

Hopefully, the tips I’ve outlined above will help you keep your eBike running fast. and for a long time. And remember:

The most significant danger to batteries of eBikes is excessive heat and low voltage. Make sure you keep your eBike battery topped up. and it will last for a very long time.

Hi I just bought a new e bike First time i have used it all was fine When i wanna charge it for 1st time there has been no charge sept by the battery. The charger la good but the battery don t keep charge The fuses(2) are good and electricity crosses the battery but don t keep charge. The company replaced the battery without see it but i liked To know if it s something To do with that problem Best regards

My ebike will cut out. I then have to remove the battery and then put it back in. The bike will run ok for a minute or two but cuts out again. I remove the battery and put it back in. It cuts out again after a minute or so. The battery still shows 2-3 bars full. Is my 4 year old battery bad, or is it some other component?

This just happened to mine. Did you resolve your issue? any suggestions? It had 2 to 3 bars when it cut out. Took battery off and back on and it powered up but quickly cut out and never powered on again. My battery seems to charge. Gonna try again, but worried it will give out again.

I have a new bolt pro ebike. At times it’s fine oother times it’ll just die on me. Today I charged it. I rode it it was fine then it would stop. The green lights wouldn’t come on. I go home put charger unn port for battery they say it’s fine. I’m getting angry maybe I should get a new battery but it’s pretty new. I come home charger is red for 30 minutes I leave it’s fine then it dies. What is rhis should I get a new charger,?

I have a rear motor hub kit 1000W 52volt and I’ve had it for about 2 years no issues untill few months ago I got a 03 error code on my ktlcd3 screen which after reading in the manual pointed to hall sensor issue, so because the sensors were only about a dollar each I just changed all three rather than testing anything and I was back on the road 100%. No just a few days ago I got the same error code so I changed the sensors again only this time I’m still getting the code 03 error. I checked out every wire took everything apart made sure everything was good nothing was touching anything it shouldn’t be I changed the sensor in the throttle. Now when I plug everything back in I’m not getting the 03 error anymore but I’m also not getting any power from the throttle and on the screen is not recognizing any battery power even though I have two battery packs both 52 volt fully charged. What could I have done I never had an issue with the battery before showing on the screen as always been accurate. I’m going to keep checking everything again I just needed to take a break before I go crazy luckily for me I’m in Ontario and it’s freezing cold outside so it’s not that big of a deal but I was wondering if you had any ideas something I could check or do to get this thing going again. Thank you for your time have a nice day

How to Charge an Electric Bike Without a Charger [6 Ways]

As we move into a new era of urban transportation led by electric vehicles, electric bikes have become quite popular amongst everyday commuters. Electric bikes are easier to use than regular bikes; they are faster, more reliable, and a good option compared to expensive electric cars.

However, one of the common problems that people face when it comes to e-bikes is how to charge them if you cannot reach your charger. Suppose your charger is at home and you are out on the road and run out of charging; what can you do in such a situation? Or what happens when your charger has stopped working for some reason, and you need an alternative solution for charging your electric bike?

Don’t let these worries dissuade you from getting an e-bike. Although it is recommended that you only use the right charger to charge an e-bike’s battery, there are a few other ways you can charge your e-bike without a charger. Read ahead for a closer look at some of those ways.

Ways to Charge an Electric Bike Without an E-Bike Charger

Most e-bikes on the market come fitted with lithium-ion batteries instead of older and less effective nickel-cadmium or lead-acid batteries.

aventon, sinch, step-through, electric, bike, charger

Lithium-ion batteries provide more power density and are easier to charge than other batteries. In general, a lithium-ion battery has a capacity of 9 amp hours and a range of 32 km.

If you ever find yourself without your e-bike charger, here are six alternative ways to charge your electric bike’s lithium-ion battery.

However, remember that these methods should only be used in an emergency and can harm your battery in the long run.

Charging the Battery with a USB Port

You can use any regular USB port charger to easily charge an e-bike lithium-ion battery. You need to find a USB cord like the one you would use to find your smartphone.

Connect the cord to an electric device with a USB port, such as a power bank, a computer, or even a wall socket. Connect the discharge end of the cord to your battery. Then you can switch on the electric device, and the battery will begin charging.

Remember, this is only a good option for a smaller battery. A larger battery might not be supported by a regular USB port cable, leading to the battery malfunctioning.

Charging the E-Bike Battery Using a Car Battery

You can also use your car battery to charge your e-bike’s battery. This method works by connecting the e-bike’s lithium-ion battery to the car’s lead-acid battery using jumper cables or any other wiring.

However, while using this method, you have to be careful of the current supply going from your car’s much more powerful battery to your e-bike’s smaller and less powerful battery.

The current supply can be controlled using light bulbs connected to the wiring.

For example, if your car battery has 13V power and your e-bike’s battery has 6V power, you can use three small light bulbs to control the current flow and ensure that the bike battery is not overwhelmed.

By arranging the three bulbs parallel to each other, you can let 0.5 amps flow to the battery.

When using this method, be careful not to leave the charging process unattended, as your e-bike battery can become overheated or receive too many amps of power. This can cause long-term damage to the battery.

Charging the E-Bike Battery Using Solar Panel

Solar panels are much more powerful than they look and can be used to charge most kinds of batteries, not just e-bike lithium-ion batteries.

Using a solar panel to charge your e-bike is only an option if you have a solar charge regulator or a high-quality solar inverter. If you do not have either of these essential parts, charging your e-bike using solar panels would be impossible.

For your safety, wear proper protective gear when dealing with solar panels. Gloves, closed shoes, and eye shields will keep you safe from electric shocks and exposed electric wiring. This may also be a two-person job if you move the solar panels and adjust their positions.

Using A Clip Charger to Charge the E-Bike Battery

Clip chargers are not as common as USB port chargers, so you may not always have one in case of an emergency. However, if you do happen to have one on hand, it can easily be used to charge your e-bike battery.

First, you have to disconnect the battery from the bike and then place it onto the clip charger’s loading station. Then you can connect the charger to the power supply and allow your battery to charge.

Only use this method of charging your e-bike if you are certain the charger is in good condition and has not fallen or been hit. If the charger is defective, it can cause damage to your battery.

Also, be careful not to touch the battery with your bare hands while it is charging in case of an electric shock.

Charging the E-Bike at a Charging Station

As e-bikes are becoming more and more popular, the production of e-bikes has gone up, along with the introduction of e-bike charging infrastructure.

There are many e-bike charging stations across the country. Many indoor charging stations are cropping up and charging stations at different restaurants and bars.

If you find that your e-bike battery is about to run out of charge while riding it, you can look up the nearest charging station and head there to recharge your battery.

You need to get to the station, remove your e-bike’s battery, and put it on charge in a suitable charging port. You can find charging stations by Shell, Hyundai, EV Box, ChargePoint, Tesla, Bosch, and other companies.

Charging the E-Bike Battery Using an Alternative Charger

And finally, the last alternative way to charge an electric bike without a charger is by using an alternative charger. This method involves using three AAA batteries in a sequence to create a charge of 4.5 volts.

A typical e-bike lithium-ion battery needs around 3.7 volts to charge, so three AAA batteries should work well enough.

While using this method, make sure that the three batteries are arranged properly to ensure proper current flow.

Also, make sure that the three batteries are giving off the same amount of power to avoid an unregulated flow of power or a charging malfunction.

These were our six alternative ways to charge an electric bike without a charger or in the case of an emergency. The easiest and most convenient of these options would definitely be to visit an e-bike charging station and use one of their charging ports to charge your battery.

This option does not require the technical knowledge you may need for some of the other options and is also the least likely to cause damage to your electric bike’s battery.

However, if you’re stuck somewhere and need to charge your e-bike to get back home, these other options are worth trying and could work out quite well.

We would also recommend that you carry an extra e-bike battery whenever you go out riding your electric bike.

Not only can this help you avoid having to find alternative means of charging your e-bike, but it can give you the peace of mind that you won’t find yourself stranded away from home with a dead battery.

E-Bike Battery Charging Tips for a Long-Lasting and Healthy Battery

Using methods to charge your e-bike other than its original charger can damage the battery with lowered battery health. Even while using the correct charger, there are certain mistakes people make.

Here are some tips on e-bike battery charging to ensure your battery stays in good health and lasts a long time.

Charge Your Electric Bike’s Battery on a Clean, Flat Surface

You should always charge your battery on a clean and flat surface. If you charge it on an uneven or elevated surface, there is a risk of the battery falling and becoming damaged. Also, charge it in a spot out of direct sunlight or any other extreme weather.

Use The Right Type of Charger for Your Battery

Depending on the size and power of your battery, you will need a specific kind of charger to charge it. Most e-bikes come with lithium-ion batteries between 36 and 48 volts, or 2 to 7 amps. These batteries come with specific lithium-ion chargers that plug into standard 110-volt outlets.

Check the Battery Levels After Every Ride

You should check your e-bike’s battery before every ride to ensure that it has enough charging, but you should also check after each ride and determine whether you need to charge it more.

If you’re not going to use the bike again for some time, it would be good to keep it on charge until the battery is above 30% charged.

Avoid Overcharging the Battery

Like most electronic devices, you have to avoid overcharging your electric bike’s battery. There is a difference between charging it regularly and overcharging it.

aventon, sinch, step-through, electric, bike, charger

Overcharging the battery is when you leave it plugged in for days at a time or when you charge it over and over again, even if the battery has only discharged by 10 or 15 percent. Overcharging the battery wears it down quickly and affects its lifespan.

Don’t Store the Bike Away On an Empty Battery

If you plan to store away your electric bike and won’t use it for around 3 to 6 months, it would be good to check the battery first.

If the battery is fully drained or charged less than 30%, you should not store the bike away. Before putting it away, charge the battery up to around 50%.

Charge the Battery Fully the First Time you Use It

If your bike is brand new or you have gotten a new battery, you should keep it to charge fully before you use it. You can plug it in for a minimum of 12 hours or leave it on charge overnight.

This will ensure that every cell in the lithium-ion battery has received a charge and will allow the battery to come out of its hibernation period. Once you start riding your e-bike with a fully charged battery, you will also get a better idea of how long the battery lasts.

Take the Battery Off the Bike to Charge It Every Few Months

Some e-bikes let you charge the battery while still on the bike. In such cases, you should still remove the battery from the bike to charge it every one or two months.

Removing the battery to charge it will allow you to check if all the connections are clean and working correctly.

Conclusion

If you ever find yourself in a tight spot where you’re out on your e-bike and your battery has run out of charge, don’t worry! We have outlined six easy alternative ways to charge your electric bike battery without a charger.

It would also be helpful for you to carry either an extra charger on you or an extra charged battery the next time you take your bike out for a ride.
