The monolithic 12V batteries do not have any PCM (any electronics) inside. They consist of finely balanced cells with identical performance. The battery must be managed and operated as a single monolithic 12V block.
We do not recommend operation in serial connection. For systems with higher voltage (24/36/48V and more), we recommend using Single cells 40Ah + BMS123Smart.
