Short-circuit protection function: disconnect the load from the recovery.
Size: 90mm * 50mm * 10mm
The main functions: Over-charged, Over-discharged protection, short circuit protection, over-current protection, with Balancing function.
The board have balancing function. So you may see a balance connector with 4 wires, below chart shows how to connect the wires onto 4 batteries to realize balancing and protection.
- The Positive output on Battery Pack (12V + )could connecting to charger positive pole (charger +)
- Battery Pack (12V -) connecting with B- on board
- Chip board P- connecting to Charger Negative Pole (charger -)
- Chip board P- could be Negative output for charger, motor, controller
- 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-“ , “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.
3, First connect the “P-“ , “B-“ to the battery pack, then re-check with the battery voltages,
Then connect the 4 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 with voltage )
1 - 2 - 3 - 4
3V - 6V - 9V - 12V
Check every voltage on the wire step by step before plug in the connector. C
heck 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 damage 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.
- Battery not including, the auction is for BMS only.
