Take care to ensure that the battery does not get too hot. Battery aging increases sharply with temperatures above 40 °C. Being placed directly in the sun’s rays can cause a battery to heat up considerably. Take care to ensure you don’t leave the battery in a hot car and park your bike in the shade during bike rides. If you cannot avoid the heat, make sure you don’t charge the battery at the same time.
A fully charged battery ages at an even higher rate at high temperatures than a partially charged one.
If you ride constantly using maximum motor power, your motor will constantly need a higher current. Higher currents cause the battery to age faster.
You can also increase the service life of your battery by using the assistance judiciously. Cycle using a low assistance setting. Lower discharge current draws will save your battery.
When not using the battery pack for a longer period, charge it to approx. 60 %.
When the battery pack is stored discharged (empty) for longer periods, it can become damaged despite the low self-discharging and the battery capacity may be strongly reduced. It is not recommended to have the battery pack connected permanently to the charger.
The lithium battery is fitted with a battery management system (BMS) which actively monitors the battery. If any of the cells get too low in voltage, it can cut the power and prevent the cell from becoming over-discharged which can cause irreversible damage. The BMS is also active during the charging of the battery and performs a similar function which prevents the cells from receiving too much charge. The BMS is also able to even out the charge between cells with what is known as “balancing” the batteries. This typically occurs at the end of the charging cycle.
