Keeping your e-bike battery in good condition ensures its performance and lifespan. To keep your battery in optimal working condition, you should charge it properly, store it correctly, and take care of it.
Avoid fully discharge:
Try to avoid fully discharging your electric bike battery until the power shuts down. It’s okay if it happens sometimes, but it should not be a regular occurrence. Lithium ion battery cells are more comfortable working between 20% ~ 80% of its rated capacity.
Most of the battery pack in the market is IP54 rated or lower. It means it cannot resist water jets directly onto the battery. In heavy rain, water may penetrate into the interior of the battery pack, causing permanent damages. The best practice is to cover up its charging and discharging ports with a plastic cover to avoid direct water downpour during heavy rain. For example, it's recommended to use a swimming cap to cover up the top part of the MC / MC-Pro battery.
Do not charge it immediately after your ride:
Immediately after your ride, the battery might be warm due to heat generated during your ride and exposure to the sun. Let it cool down for half an hour at home before charging it.
Keep it charged when not in use:
When you aren’t using your e-bike for a long time, make sure to keep some juice in it. It is best to store them at a minimum voltage of 3.6 or 3.7 volts per cell, or at around 36-37 volts for a 36v battery / at 47-48 volts for a 48v battery, when it’s not in use for the long term. Check the battery voltage once a month and make sure it does not have noticeable drop in voltage. It's recommended to recharge it for 5-10 mins once every three months.
Store at correct temperatures:
Besides storing your battery partially charged when it’s not in use, you’ll also want to be wary of the temperature it’s kept in. Higher temperatures can negatively impact your battery’s lifespan and performance. Store batteries at a cool and dry environment , preferably between 0°C and 20°C to ensure it’s performance and safety.
Correct Way to Charge your Battery:
1) Turn off the power switch at the power socket
2) Plug the 3-pin plug of your charger into the power socket.
3) Plug the DC connector of your charger into the battery
4) Turn on the power switch of the power socket. You should see the LED indicator on your charger turns red. A red LED means the battery is being charged.
