1. Product Positioning & Basic Advantages
This 12V 400Ah lithium iron phosphate (LFP) battery is specially developed for power supply systems of modified special vehicles including RVs and engineering vehicles. It is also compatible with various off-grid power supply scenarios such as UPS power supplies and electric equipment.
With an integrated BMS (Battery Management System) and domestically sourced Grade A battery cells, the product delivers high safety, stable performance and an extended cycle life.
2. Core Product Functions
It is equipped with multi-layer safety protection mechanisms to avoid abnormal risks such as overcharging, over-discharging, overcurrent, excessive high temperature and low temperature.It supports high-current discharge and capacity expansion by parallel connection of multiple identical batteries.It comes with an external charging wake-up function: the battery will automatically activate once an external charging power supply is connected.A built-in low-temperature heating module guarantees normal charging and discharging operations in low-temperature environments.
3. Unit Interfaces & Status Display
The battery is equipped with external RS485 & CAN communication ports, dedicated multi-unit parallel communication ports and a remote switch interface.Multiple groups of LED indicator lights are integrated to display operating status, fault alarms and residual battery capacity, enabling intuitive viewing of remaining power and battery working conditions.An optional remote on/off control panel is available. The battery can be switched on and off through two control modes: physical buttons on the unit or remote switches.
