Overview: 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.
Product Technical Features:

Fully sealed design with a die-cast sealed aluminum shell for waterproof and dustproof protection.
Wide operating temperature range with a built-in low-temperature heating function, operating range from -40 to 60°C.
Comprehensive control and protection functions, including over-voltage, under-voltage, overcharge/discharge current, high/low temperature, and short-circuit protection for the battery pack and individual cells, along with various alarm functions.
Supports RS485 and CAN communication functions.
High-precision detection of voltage, current, and temperature.
Standby sleep function that keeps the system in low-power mode when not in operation.
The battery can disconnect and connect the battery bus via an external switch.
Direct parallel expansion capability with similar batteries.
