Feature

●Product Character:Active balancing function, no need to lose battery capacity to compensate for the voltage difference of sales, increase battery usage efficiency by 95%. It can be used with 4-8s ion/cobalt acid lithium/manganese acid lithium/lithium battery packs. It has the protection against overcharge/over-discharge/over-current and short circuit etc.
●Working condition: Working temperature: -20~70℃; Power requirement: 24V~100V, can be powered by battery power or external power supply; Power dissipation: In balance: 10mA & 100V, no balance: 6mA & 100V
●After connecting the BMS, please use the power supply, which is 5V as the battery voltage to activate it
●This is an active BMS, it supports 3S-8S of ions and 4S-8S of LiFePo4. 200A continuous current, it also has 2A active compensation current. It can set up the compensation voltage and discharge protection parameters via the app. It can display the individual series of battery voltage
●Note The 485 converter is only for transferring communication to RS485, it cannot be directly connected to the PC, it needs to be connected to another 485 module to connect for PC. The yellow cable is for 485A, the white cable is for 485B, the black cable is for GND and you do not need to connect the black cable.
