Waring:
- In case of high constant current more than 10A, it’s strongly recommended that additional protection components to protect the battery itself, for example, polyswitch, NTC, fuse,etc.
- The safety PCM is specially designed for professionals. Mis-understanding and abuse use may cause battery damaged or over-heated, even exploded.
- Please don’t use the PCM for lower capacity or low drain LiFePO4 pack. Make sure your LiFePO4 Battery pack can handle 20A drain current before buying
- To achieve balance, each cell in battery pack must has equal voltage within tolerance of 0.2V.
