BMS (Battery Management System)  
The battery is equipped with a BMS. This regulates the charging and discharging phases (including balancing of the interconnected individual cells) and protects the battery from overvoltage and under voltage.  

Charging/discharging cycles  
The specified charging cycles are not the same as the number of charging cycles. If, for example, the battery is charged twice with 50% charge, this corresponds to only one charge cycle. Important! Charge your battery fully before using it for the first time and use it until there is only a remaining capacity of approx. 10%. 

Generally, a Li-Ion battery should never be completely discharged. Otherwise, there is a risk of deep discharge, which can irreversibly damage the battery. It is therefore advisable never to discharge the battery completely, despite BMS, which could switch off too late due to different external influences (temperature, age of the cells, defective cells due to external influences, etc.).  

Correct storage  
If you do not use the battery for an extended period of time, store it in a cool, dry place. The battery should be charged to approximately 45-60% during storage and connected to the charger for one hour every 6 weeks.
