The 20S series intelligent BMS protection board is specially designed for 48V, 60V, 72V, 84V lithium battery application scenarios, suitable for ternary lithium, lithium iron phosphate and lithium titanate batteries.
The BMS supports RS485 and CAN communication, RS485 supports Modbus protocol, CAN protocol supports CANOPENand 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.
The BMS externalBluetooth module, through the Android mobile phone Bluetooth APP software can view and set various parameters of the BMS.
