Remarks:

  • The PCM is specially designed for LiFePo4 4S 12.8V with 100A discharging rate. It’s different from others, whose balance function is set to ensure battery  fully charged and safety.
  • PCM will detect each cell’s voltage and trim higher voltage down until other cells reach the same voltage level. Therefore, it helps batteries have longer service life.
  • 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.
