20 String 45A 72V 84V Lithium Battery Protection Board with Balance Board

Description:
20 String 45A 72V 84V Lithium Battery Protection Board with Balance Board

Specification:
Heat sink size: 120 * 60 * 9mm
Cable length: 400mm
Electrical parameters: As shown in following table

Features:
-With a balanced, same port 45A discharge.
-Protection board with overcharge protection, over discharge protection, over current protection, short circuit protection, temperature protection.

Attention when connecting:
-When we connect BMS with cells or disassemble BMS from battery pack, the following order and regulations must be complied with to avoid damage of components of BMS and problems of not protecting of cells.
-In order to achieve the best performance of BMS and to run the longest distance, all the battery must be matched well (Each battery voltage ≦0.05V, IR≦15 mΩ,capacity≦30mAh) to make sure the better consistency of the battery.
-Cell must be connected in parallel first, after then connected in series

Order of connection:
Step1: Connect charging /discharging wire , battery pack negative wire
Step2: After confirm the wires are connected OK, plug the connector cable in the BMS
DO NOT plug CONNECTOR CABLE in the BMS before connect wire!!

Attention, ESD protection during work
Electrical parameters: (Lithium ion battery) (20 string)
