Note

Due to this BMS is not properly compatible with Relay and Inverter, occasionally it warns "Current sensor abnormal" or the current is not accurate when the BMS connected to Relay or Inverter, please ignore it
if you really care about it, please do not purchase, otherwise we will not accept any refund, Thanks!

Description

This is an Active BMS, it supports 3S-8S of Li ion and 4S-8S of LiFePo4
200A continuous current,
It also has 2A active equalization current
It can set up the equalization voltage and the charge & discharge protection parameter through APP,
It can display the single series of battery voltage
After connected the BMS, please use the power supply which is 5v greater than battery voltage to activate it

Product character

1.Active balance functionality, no need to lose the battery capacity to balance the voltage difference of sells, raise the battery usage efficiency for 95%
2.It can be used on 4~8s li-ion/Cobalt acid lithium/Manganese acid lithium/Lithium iron battery packs
3.Constant working current is 200A
4.It has the protections of Over-charge/Over-discharge/Over-current and Short circuit etc.

Working condition

Workable temperature: -20~70℃

Notice: The 485 converter just for transfering the communication to be RS485, it can not be connected to PC directly, it needs to connect to another 485 module to connect to PC, The yellow wire is 485A , the white wire is 485B, the black wire is for GND and you don't have to connect the black wire, We will provide you the 485 protocol after bought the 485 converter, and we don't provide the software, if you are not the familiar with Serial Port Debugging Tool, please be careful when you want you purchase this product
