BATTERY MODULE STORAGE
1. To ensure the battery service life, the storage temperature shall be kept between 0°C~35°C. The battery
shall be cycled at least once every 6 months.
2. To minimize self-discharge in a long storage period, disconnect the BATTERY connection (1/2) of the
high-voltage control box of the DC connecting cable. This will interrupt the use of the 12 V power supply
installed in the high-voltage control box and prevent the battery from self-discharging.
