  • The PCM is specially designed for 3S 11.1V Li-Ion battery 30A 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 over-heated, even exploded.
