Where does the BMS use?
Where do I use BMS?
Put it where your battery is.pls check the connection diagrame below.pls confirm is a common port or a separate port BMS.
NOTE:Pls kindly follow up the guide,in case the battery gets burnt by short circuit.
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.
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,250A current.common port with cooling fan.
The fan is not working until the temperature at 50 degree to save the energy consumption at low temperature.

What smart/soft function does it have?
There are severl options for the smart BMS,which you can have different function from it.Deligreen's smart BMS has CAN/UART/FAN,and LCD control.It denpends on what protocal of your battery is.We will supply the relevant cables for the connection,UART,USB.CAN.
Q:Which current of the PCB should i choose?
A:Take 13S 48V pack as an example: Which PCB you should choose depends on the power of your motor or the current limitation of your controller. Below 350W ,you can choose 16A.Below 500W, you can choose 18A, Below 800W, you can choose 35A,Below 1KW, you can choose 60A. Above 1200W, the same. If you are not sure, please contact us freely.
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
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.
What is battery management system BMS?
Where to buy battery management system?
Pls go to the bottom of this page,and send us your requirement,we will contact you by email or whatsapp to recommend the BMS you need.We can ship to you freight charge included.
How does battery management system work?
The battery management system monitors battery conditions and takes actions to extend battery life. If excessive battery drain is detected, the system temporarily disables some electrical systems to protect the battery.
