Before you placing the order.
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
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.

What is battery management system BMS?
What is 4S12V 250A Common Port?
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.
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.
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.
Changsha Deligreen Power Co.LTD,founded in 2010,is a "Green Energy Solution Service Provider".
