Sodium ion Battery BMS Wiring Diagram

1, Start from the black balance wire, to connect it to the negative (B- as shown) of a sodium ion battery pack.
2, Then connect the first red balance wire that's next to the black one to the positive of the first series of the sodium battery pack.
3, Connect the second red balance wire to the positive of the second series fo the na ion batery pack, and so on, to the last red balance wire to the positive of the na battery pack (B+ as shown).
4, Use a multimeter to check each balance port and make sure each cell's voltage is correct.
5, If everything is correct, put the balance plug in the port of the BMS.
