1) Introduction and Features：
This is a Smart protection board specially designed for battery packs of.It can be applied to lithium batteries with different chemical properties, such as lithium ion, Li-polymer. Lithium iron phosphate, etc. The protection board has strong loading capacity and the maximum continuous discharge current can reach 200A or 300A.
- 7S to 20S cell protection for Lithium Battery pack (Series no*4.2=Battery full voltage cell series numbers*3.65= Lifepo4 battery pack voltage ),client can select suitable type based on your battery characteristics,this BMS can automatically recongize the battery series number .
- Constant current : 200A or 300A constant current can be selected based on your demand ,.
- Auto level front detection chip with high detection precision degree ,with dual AD design for the chip and more safe and more reliable in working performance
- Various protection functions for charging and discharging ( over-charge , over-discharge ,high or Low temperature protection ,over-current protection , short circuit protection etc ) with double layers protection hardware and software protection .
- We adopted the electric relay solution for power controlling switch instead of Mosfet for large current application . it will be more reliable
- Precise SOC calculation with SOC function of automatic learning
- Automatically charge battery function or static balance function for the battery system
- Equipped with Bluetooth communication function for monitor all battery information clearly from APP or PC .( RS485 communication and CAN communication can be added on this board if needs )
- with reserved Swith function to controlling the battery output ,the discharge cotrolling switch will prevent fire sparking when connects charger .
- when the battery rest time reached its setup time of the rest . the bms will turn off and went to sleep mode so as to low the current consumption in rest period .
- Not support parallel connection ( for the parallel connection ,the higher voltage pack will discharge large current to the battery pack with lower voltage , so it will be dangerous )
- Weight :1.5KG
Default Parameters setting :
Specification as below is our defaul setting value , clinet can use the PC module to set them on yourside without
problems .if you want us to set it , you can leave a message to us based on your battery specification without problems
A.Mobile Phone APP Display and how to set parameters via APP software with the Bluetooth Communication module as below.
What Bluetooth Communication Module can do ?
With Bluetooth Communication Module , the APP Software can be connected , and all information of the BMS can display on your Mobile Phone . and you can set some parameters on Your APP software :Over-protection voltage , Over-discharge protection voltage Rlease voltage of over-charge and discharge .
Adroid APP :
