  • The main functions are: overcharge protection, over-discharge protection, over current protection, short-circuit protection, temperature protection etc.
  • Keep your battery long cycle service lifetime. The heat sink will greatly help to cool. IC itself has a power balancing function. The circuit is simple and reliable.
  • Typical voltage detection for each cell. So each battery will be prevented over charged or over-discharged. Over current and short circuit protection.
  • A long time short circuit of the load won’t affect the PCB and the battery. Temperature protection during charging and discharging.
  • Extreme low power consumption. The consumption of the whole device is less than 50uA.
  • PCB use high anti-corrosion, high water resistance, high impedance ESD conformal Coating.
