    Batteries for Electric Scooters: 18650 Vs 21700

    E-scooters are fitted with batteries which are like the gas tank in automobiles. They store energy that powers up the motor and other components such as the controllers, display, headlights. Usually, numerous individual cells are assembled to form a battery pack embedded deep inside the deck or stem of the scooter.

    The majority of e-scooters have a battery pack comprising lithium-ion battery cells. However, some inexpensive e-scooters, especially those for kids, are fitted with lead-acid batteries.

    21700, ebike, battery, pack

    650 and 21700 Batteries Explained

    The battery is the most important part of an electric scooter, so understanding what you’re getting with each option is critical if you are trying to get the best value possible. Here’s the reality… there are benefits and drawbacks to both 18650 and 21700 batteries, so choosing between them requires an in-depth look at how they measure up to one another in various categories. The chances are that your existing or future e-scooter will likely come equipped with either type of battery, but it’s essential to know the differences.

    Lithium-ion batteries are preferred mainly on e-scooters thanks to their ability to deliver a higher capacity output with fewer cells. The vast majority of battery packs for e-scooters comprises 18650 and 21700 cells. 18650 cells were first developed in 1994 by Panasonic and quickly became the preferred standard for electronics across the globe. However, 21700 cells have become the preferred standard in recent years, especially in e-scooters with powerful motors due to their higher capacities and discharge rates.

    18650 and 21700 are rechargeable Lithium-ion cells named based on their diameter and length. 18650 cells measure 18mm in diameter and 65mm in length, hence the name 18650, while 21700 batteries measure 21mm in diameter and 70mm in length, hence the name 21700.

    Both batteries are available in flat top and button top forms. However, they are pretty different, even in their physical aspects. 18650 batteries are slightly smaller than 21700 batteries. Being marginally more significant, 21700 batteries store more energy and offer a higher discharge rate than their counterparts.

    18650 batteries and 21700 batteries also have different mAh capacities. mAh’s on 18650 batteries will range from 2000 to 3500, while 21700 batteries have mAh’s ranging between 3000 and 5000. These batteries can be either protected or unprotected. Protected batteries are integrated with preventive mechanisms (battery management systems) such as overheat protection and PCB, which safeguard against overheating and overcharging. These mechanisms come in handy to make the battery safer for use and also prolong its lifetime.

    650 Batteries

    18650 batteries are lithium-ion rechargeable batteries used to power portable electronic devices such as electric scooters. These batteries are the predecessors of the most recent 21700 batteries, which generally have a higher capacity and discharger rate. However, this doesn’t mean that they are less efficient or can not be used in modern e-scooters.

    18650 cells have a diameter of 18 mm and a length of 65 mm. They have a standardised market size of 3.6 and 3.7 volts with a capacity of between 2000mAh and 3500 mAh. They can store about 10 to 13 Watt-hour (Wh) with such ratings. A 18650 battery marked as 3.7 v 18650 3000mAh means:

    • The peak voltage is 3.7v.
    • 18650 is the dimensions of the battery.
    • 3000mAh is the charge capacity in amp-hours that the battery can provide.

    Some phrases can also be added to the battery’s information section, such as “protected mode”, meaning that it’s fitted with an overdraw or overcharge circuit protection and “low self-discharge” to indicate that it can hold a charge in storage. Protected batteries are integrated with the protective electronic circuit in the battery casing to prevent issues such as overheating and overcharging. These issues may ruin the charger, and worse even, cause harm to the users through fire incidents and explosions. While unprotected 18650 batteries are cheaper, they are not usually recommended as they can easily overheat, explode or start a fire.

    The charge time for 18650 batteries varies based on the specific type of battery and the charger in use. Usually, it takes about four hours for a 18650 battery to charge fully. Apart from e-scooters, 18650 batteries are used in several gadgets, electronics and accessories, including laptops, high lumen flashlights, vaping devices and more.

    What’s the Time Taken to Charge a 18650 Battery

    The time a 18650 battery takes to charge depends mainly on its capacity and the type of charger used. As outlined earlier, 18650 batteries have a capacity ranging from 2000 to 3500 mAh. At maximum capacity, at the 3500 milliamp level (mAh), it takes approximately 4 hours for the battery to charge fully. This charging time may drop to even 3 hours when using a fast charger.

    Take note that the charging time varies based on the battery capacity and the type of charger used. What’s more, the charging time increases as the battery gets older. This is also accompanied by a decreased ability to hold a charge.

    The time taken to charge the battery and the charge holding capacity are factors that can be used to indicate that the battery is dying. So, if you notice that your e-scooter takes a longer time than it usually does or it offers fewer miles per charge, it may be time to get a new battery.

    18650 Battery LifeSpan

    A standard 18650 battery has a lifespan of between 300 to 500 charge cycles. This means they can be recharged from as little as 300 to as many as 500 times before they die. A Lithium-ion battery pack is considered dead when it can no longer hold any charge.

    While 500 cycles are the standard lifespan for 18650 batteries, a cell’s lifespan is dependent on several factors such as the frequency of recharging, amount of time they are in use and how they are cared for.

    For the most part, the lifetime of an individual 18650 battery is dependent on two main components: the amount of time the scooter is used with energy being drawn from the battery and the number of times the battery is charged. These two factors go hand in hand. If you frequently ride your e-scooter, then you’ll be charging the battery regularly. Frequent recharging damages the cathode causing the battery to lose its capacity.

    Nonetheless, it’s possible to increase the lifespan of a 18650 lithium battery pack through best practices such as preventing the battery from draining completely (deep discharge), removing the battery from the charge immediately it reaches capacity, charging the battery just before use and charging only when it’s below 50%. Actions such as charging the battery at freezing temperature, overcharging, and under-charging can significantly reduce the battery’s lifespan.

    How Much do 18650 Batteries for Electric Scooters Cost?

    18650 batteries for e-scooters cost an average of 20-100. However, the price is primarily guided by several factors such as the brand, model, quality, capacity and more. Brands such as LG and Samsung are pretty expensive but manufacture the highest quality battery cells.
