Technical Parameters:
Balanced current: 60mA (VCELL = 3.90V when)
Balanced for: 3.50 ± 0.05 V
Over-charged Protection: 3.85 ± 0.05 V
Over-discharged Protection: 2.1 ± 0.05 V
Over-charged delay: 1 ± 0.5S
Over-charged release: 3.80 ± 0.05 V
Over-discharged threshold: 2.10 ± 0.05 S
Over-discharged delay: 100 ± 50mS
Over-current Protecton: 80 A
Supports Max. Continuing Discharge Current: 80A
Static power consumption: less than 200uA
Short-circuit protection function: disconnect the load from the recovery.
Dimension: 182mm * 85mm *40mm
Feature: With Aluminum Protected Outer Shell and built-in Radiating board
The main functions: Over-charged, Over-discharged protection, short circuit protection, over-current protection, with Balancing function.
Interface Definition: The board have balancing function. So you may see a balance connector with 20 wires, when you do the connection for the 20S batteries, start from the first Red wire, then connect other Grey wires one by one, dont make wrong orderly as this will get the BMS burnt, check battery voltage step by step, it start from 3.2V and increases with (3.2V~3.6V) one by one to make 60V (64V) finally. Check every voltage increase with below parameter:

3V - 6V - 9V - 12V - 15V - 18V - 21V - 24V - 27V - 30V - 33V - 36V - 39V - 42V - 45V - 48V - 51V - 54V - 57V - 60V

The 2 thick Black wires connect to battery pack Negative, and 2 thick Yellow wires for Motor / Controller ( Discharge) Negative, and 1 thin Yellow wire for charger Negative.

Charge & Discharge Positive could be the same output.

The BMS only works for Brand new good quality battery with perfect performance, it cant work for fake capacity and used batteries. 

Check every voltage on the wire step by step before plug in the connector.  Check every wire and see if the orderly are correct. Because if any of the wire get a wrong order, it will get burnt. Smoke shows board already get burnt for protecting the battery being damaged by wrong connection,  For DIY assembling. Please make sure you are capable to do the assembling before ordering! If you dont know how to do the connection, DONT ORDER IT!
  • The BMS only use for new and consistent high drain batteries. 
  • Do not use for battery packs that mix with new & half-used, or mix with different brand battery cells.
  • Do not use for used and imbalance battery cells.
  • Do not use for batteries with fake capacity.
  • Do not touch the board by hand while it is charging / discharging.
  • If you charge the battery by LiFePO4 Balance Charger, then there's no need to use BMS.
Battery not including, the auction is for BMS only.
Balance Connector will send together with the BMS.
