MOS-4S200A

Collect

The MOS-4S series of smart BMS protection boards are specifically designed for 12V lithium battery application scenarios, suitable for ternary lithium, lithium iron phosphate and lithium titanate batteries.
BMS supports RS485 and CAN communication, RS485 supports Modbus protocol, and the communication is isolated, which effectively protects user application scenarios.
The BMS adopts the automotive BMS architecture and multiple safety protections to effectively improve the safety of lithium battery application products.
BMS external Bluetooth module, through the Android phone Bluetooth APP can view and set the parameters of the BMS.
