Short-circuit protection function: disconnect the load from the recovery.
 
Dimension: 129mm * 53mm
 
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 12 wires, below chart shows how to connect the wires onto 12 batteries to realize balancing and protection.
  1. The Positive output on Battery Pack (36V + ) could connecting to charger positive pole (charger +)
  2. Battery Pack (36V -) connecting with B- on board
  3. Chip board P- connecting to Charger Negative Pole (charger -)
  4. Chip board P- could be Negative output for charger, motor, controller
  5. Battery B+ could be Positive output for charger, motor, controller

1,  The charging port and the discharge port of the board are the same Positive port. “B-“ for negative Pole of the battery pack, “P-“ is negative pole for both discharging and charging. 
 
2,  “B-“, “N-“ , “P-“ welding pad are through-hole port, hole diameter of 3.5 mm; You could use solder iron to weld the wires through the hole port, Every charging port for battery are the DC needle seat forms output. “N-“ with no wiring when charging and discharging are in the same port;
 
3,  First connect the “P-“ , “B-“ to the battery pack, then re-check with the battery voltages, then connect the 12 wires onto the batteries, Do not connect in wrong ordering, or it will burn out the board.
 
If you made wrong connection and reverse the board that will cause smoke, please check with every wire to be sure you are doing correct connection. 
 
check all the wires voltage with orderly, start from B- , and see if it increasing from 3.2V, like:
( wires / voltage )
1    -  2   -  3  -    4   -   5    -   6    -   7   -   8     -   9   -   10   -  11   -  12  
3V - 6V - 9V - 12V - 15V - 18V - 21V - 24V - 27V - 30V - 33V - 36V    
 
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!
 
 
IMPORTANT!!!
  • 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.
