Hardware Smart Battery Management System 4S12V 120A With Fan
Know about 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.This is a very worthy of money to
make your battery packs a BMS.
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.
Which current of the PCB should i choose?
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.
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,150A current.common port with cooling
fan.
Smart BMS is a new product in 2020,upgraded the hardware
BMS,besides the LCD display,warning,voltage,current function.It
upgrades CAN,GPS,UART,485,Bluetooth function,it can connect your
PC,mobilephone etc.
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

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.

FAQ
Q:Can i use bigger size of PCB than it should?
A:Suppose you need 60A PCB but you chose 80A, that is OK.
80A allows higher current.Nothing bad but a bit higher price.
But if you choose 50A, sorry it is too small. So you can choose
higher spec but can’t choose lower one than it should have been.
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.
