4S12V 80A Common Port Battery Management System BMS

Lifepo4 Lithium Battery Management System BMS 4S12V 80A Common Port

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.

Specification

The separate parts of smart BMS

• Two wheels style heatsinks
• Wave style heatsink
• High current board(with 3mm pure copper port)
• BMS PCBA
• Thermally conductive silica gel
• Pure aluminum heatsink

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+;

• Do not insert the connector directly after the wires were connected. Measure the voltage between two adjacent metal terminals on the back of the connector. If it is Li-ion battery, the voltage should be between 3.0 ~ 4.2V, Lifepo4 battery should be between 2.0 ~ 3.6V, and LTO battery should be between 1.5~ 2.75V;
• After the wiring sequence and voltage are confirmed to be correct, then insert into BMS; .
• Adjust the multimeter to the buzzer position and measure the internal resistance between B - and P -when the internal resistance is 0, there will be a beep, which means that the BMS is good. Otherwise,do not weld and contact the customer severice.;
• The last step to connect B-(thick blue wire) with battery pack's total negative pole.

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.
