 Storage relative humidity range：5%~70%.
 Store in a dry, clean, and ventilated environment, away from
direct sunlight.
 When storing the battery module, place it correctly. Do not put
the battery module upside down or on its side.
 If the battery module is stored for a long time, replenish the
power supply periodically. Battery module power supply
requirements: the charging current is less than or equal to 7A,
and the battery module needs to be charged to 50%SOC.
