The appearance and dimension of BM-12-38.4/280
a. The battery module can be used alone or multiple in series. When connecting in series, pay attention to the correct connection of the positive and negative terminals, otherwise, it may lead to damages or safety hazards.
b. Battery module used in series must be charged or discharged at the same time to keep the consistency of cells.
d. The battery module must be operated within the specified discharge conditions. Overdischarge will lead sharp decrease in the battery capacity and overheat the battery, resulting in battery damage or safety hazards.
e. The battery module must be operated within the specified environment conditions, since too high or too low ambient temperature will affect the performance of cells.
