Connection diagram
Smart BMS 4S LIFEPO4 12V BMS,ranges 80A-500A,common port,separate
port.
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.
Focus on lithium rechargeable battery,BMS,Balancer,charger and
relative products.
BMS is one of best sellers,we've been receiving thousands of good
comment from our clients because of its good quality and function
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.
