1. Water and dustproof, die-cast sealed aluminum shell, fully enclosed design.
   
   
2. Operating temperature ranges are wide, and the heating function at low temperatures is embedded; operating range -40 to +60°C.
   
   
3. Comprehensive protection functions: over-voltage, under-voltage, overcharge/discharge current, high/low temperature of the pack and cells, short-circuit protection, and multiple alarm functions.
   
   
4. Supports RS485, CAN communication.
   
   
5. High accuracy of voltage, current, and temperature detections.
   
   
6. Standby sleep function keeps the system in low-power mode when not in operation.
   
   
7. The battery can disconnect/connect the battery bus via an external switch.
   
   
8. Direct parallel expansion capability with similar batteries.

The HJ4850L modular battery from Huijue Group adopts a 48V lithium iron phosphate battery with a modular design. It is suitable for assembled power modules, featuring high energy density, long life, safety, and reliability. It integrates a BMS (Battery Management System) protection board, providing multiple protection functions and intelligent management. It supports RS485 communication, offering high-precision detection and SOC (State of Charge) estimation.
