10S 36V20Abms is used for 10series 36V battery pack. design it for various lithium batteries like LiFepo4, LiMn2O4, and Li-polymer etc. The main functions are: over charge protection, over discharge protection, over current protection, short-circuit protection, temperature protection etc. manufactured by high quality Mos and IC . Keep your battery long cycle serivce life time. Strong load ability, constant discharge current 20A, use high voltage resistance, low inner resistance power Mosfet. The heat sink greatly help cooling. IC itself has power balancing function. The circuit is simple and reliable. Typical voltage detection for each cell. So each battery be prevented over or over discharged. Over current and short circuit protection function is very reliable.Long time short circuit of the load '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-, high water resistance, high impedance ESD conformal Coating.
