JIKONG JK-QB2A8S20P – 2A Balancer 200A BMS for 4-8S Truck Batteries

The protection board adopts active equalization technology, and the principle of equalization is to transfer the energy of the high-voltage cell to the low-voltage cell, and realize the energy transfer through the medium of the protection board. Before using the balancing function, users need to set the basic parameters of the battery and download the extreme space BMS-APP. After downloading, set the battery type on the parameter setting page of the extreme space APP. For default parameters, see Chapter 4.
Users can set the balance trigger pressure difference (mV) in the parameter setting of the APP. When the balance is turned on, the balance will be turned on automatically when the pressure difference of any two strings of batteries in the battery pack is greater than the set value, and the balance will be turned off when the pressure difference is less than the set value. The default balance current is 2 A. Users can adjust the balance current according to their own battery capacity. It is recommended that the balance current not exceed 0.2C of the battery capacity (C). If you do not need the balancing function, you can set the balancing switch to off in the BMS control page of the APP.
