Remarks:
- The PCM is specially designed for LiFePo4 4S 12.8V with 20A discharging rate.
- In case of high constant current more than 10A, it’s strongly recommended that additional protection components to ensure safety, for example, polyswitch, NTC, fuse,etc.
- The safety PCM is specially designed for professionals. Mis-understanding and abuse use may cause battery damaged or overheated, even exploded.
