It is an intelligent protection board scheme specially designed for 4 series battery packs of start-up battery and electric energy storage products.It is suitable for lithium batteries with different chemical properties, such as lithium ion, lithium polymer, lithium iron phosphate, etc.The protection board has strong load carrying capacity and the maximum continuous discharge current can reach 120A.
● 4 cell series protection
● Various protection functions for charging and discharging
● Discharge over current, short circuit protection functional processes of hardware
● Over voltage, under voltage, temperature and overload protection function processing of software
● Accurate SOC calculation with automatic SOC learning function
● Reserved RS485, CANBUS communication
● UART communication function, can read all data of battery in real time and upgrade online
● Very low static current consumption
● The reserved switch controls the output of protection board
