Strong load ability. Constant discharge current 45A. Use high voltage resistance, low inner resistance power Mosfet. The heat sink will greatly help cooling. IC itself has 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 function is very reliable. 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 40uA. PCB coated with high anti-corrosion, high water resistance, high impedance ESD. The temperature drift is extremely low, and the accuracy is 1% high power package sense resistor. It adopts sealing and waterproofing technology. Dustproof, shockproof, anti-extrusion. Its service life is twice that of ordinary protective plates. Package Included: 1 x BIKIGHT 20S Li-ion Battery Board
