The battery pack in your e-scooter contains the “fuel” required by the electric motor. The majority of e-scooters use a lithium-ion battery. This type of battery has no memory effect, don’t self-discharge and have high capacity, so they're perfect for electric scooters.
The battery pack is made up of individual cells, not too dissimilar to what a typical battery looks like. To increase the range of e-scooters the battery capacity needs to be increased by adding cells to the battery pack. This however increases the cost, size and weight of the battery pack as well as its charging time.
Battery capacity is measured in watt hours (Wh), this is easily calculated by multiplying the battery’s voltage (V) by it’s amp hours (Ah).
Wh = V x Ah
A battery's Wh rating can be used to compare batteries with different Voltages and different charge capacity (Ah) ratings. But don't forget to also compare the weight of the battery and cost. The battery with the highest voltage (V) rating or capacity (Ah) isn't always the "best" - there are multiple factors that need to be taken into consideration.
Electric scooter batteries have a battery management system (BMS) in order to make sure the battery is charged and discharged safely and to allow the power to be delivered as efficiently as possible.
The cells in electric scooter batteries are manufactured by only a few Japanese and Chinese companies. You’ll also find Chinese battery technology in the latest electric vehicles including Tesla cars.
Batteries are only one of the components to check when looking to purchase an electric scooter. Another major factor in an electric scooter’s performance and range is the motor. For a guide on electric scooter motors click here.
Your e-scooter is supplied with a lithium-ion battery (li-ion). These batteries have a high energy density allowing a lot of energy to be stored compared to the size of the battery pack. The batteries also have no memory effect, a feature found in other types of batteries that results in the charge capacity being reduced over time. Lithium-ion batteries also don’t self-discharge compared to other battery types.
Here are some simple tips to help you look after your battery.
● Don’t drain it completely: e-scooter batteries are designed differently to your mobile phone battery.
● Keep topped up and every 5-10 charge cycles drain completely. Only use the official, supplied charger. If required we can supply replacement or additional chargers. Not all chargers are the same, even if they look identical.
● Try not to charge immediately after using your e-scooter. Let the battery cool down for 10-15 minutes before charging.
● If possible charge your battery inside (above 10°C) as batteries don’t like the cold. Your charger will have a green light when battery is fully charged. Your battery will charge up to 75% fairly quickly while the final 25% will take longer.
● If storing your scooter for extended periods, i.e. over winter then don’t forget to top it up every few weeks.
