Smart BMS Lithium Battery Management System 4S12V 80A Common Port with fan

What is 4S12V 80A Common Port with fan?

This is a smart battery management system,which monitor and control the status of the batteries&battery pack.It's a lifepo4 battery BMS,4 batteries in series,12V,80A current.common port with cooling fan.

The fan keeps the battery pack cooling down when is hot.

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.

About US

Changsha Deligreen Power Co.LTD,founded in 2010,is a "Green Energy Solution Service Provider".

Newest technology,new idea,hard-working and honest people.

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.

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

FAQ

Q:What battery types do your BMS work with?

A:Our BMS can work for lithium phospate battery(Lifepo4)and NCM battery,lithium ion battery,ple let us know what your battery type before placing order.

Q:What BMS range can you supply?

A:Deligreen is a professional BMS supllier with abundant BMS range.Series from 3S-32S,Current from 10A-500A,if you need more series,pls contact us.

Q:How to choose the BMS that I need?

A:You need to make sure of following

   1. battery type

    2. charge current

    3. discharge current

    4. battery pack(series,parallel)

    5. Peak discharge current

Q:Can I watch the battery status from my mobile phone?

A:Yes,this is waht a samrt BMS do,you can watch the status of your batteries in your APP throush bluetooth connected between phone and the BMS.
