What is battery management system BMS?
Deligreen BMS is defined as an electronic system that manages a rechargeable battery(lithium phosphate,NCM battery,single cell or battery pack) by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and/or balancing it.
Why do we need battery management system?
Battery Management Systems are the brains/CPU behind battery packs. They manage the output, charging,discharging and provide notifications on the status of thebattery pack. They also protect the batteries from damage.
Smart BMS 4S LIFEPO4 12V BMS,ranges 80A-500A,common port,separate port.

The separate parts of smart BMS
Connection diagram
1, PIs do not insert balance wires into BMS before connecting batteries, must make sure connecting with batteries correct.
2, The sequence of connecting wires for BMS:
Notes: PIs ensure to use balancing wires from Daly!
1. From thin black balance wire to start, the 2nd wire(thin red wire) connect with the 1st battery's positive pole. Then connect each ell's positive pole in order until the last one B+;
After finished wiring:
Measure whether the B + and B-voltage and B + and P-voltage of the battery are equal, If yes, it means the BMS works normally and can be used. If not, please recheck according to the above wiring sequence.
