2. Product Introduction
2.1 Brief introduction
M12-400 is a 12V lithium battery with a battery capacity of 400Ah. The positive electrode of the
battery is made of lithium iron phosphate (LiFePO4) material. It configures high-performance and
high-reliability BMS to effectively manage the cells, including cell overvoltage, under-voltage,
charge over-current, discharge over-current, over-temperature, low temperature, short circuit and
other protection functions. It also has built-in cell voltage balance, capacity calculation, SOC
calculation, cycle life accumulation and low temperature heating functions. It is suitable for energy
storage systems of vehicles, ships etc.
2.2 Features

The positive electrode of the battery is made of lithium iron phosphate (LiFePO4) material,
which has good safety performance and long cycle life. 3000 cycles @ 25
℃
.

High-performance BMS with over-discharge, over-charge, over-current, temperature and
other protection functions. With automatic charge and discharge management and single cell
balance function.

Supports maximum 300A discharge current .

Supports up to 4 units in parallel, so that the total capacity can reach 12V 1600Ah

With external charging activation function. In the shutdown state, when there is an external
charging request, the battery can actively wake up, and allow charging and prohibit
discharging;

It can be equipped with battery switch or remote control panel for battery switch and battery
status (voltage, current, SOC) display.

The battery has low self-discharge rate. The standby power consumption after the battery is
turned on is <50mA, and it can be reduced to <0.1mA after the battery is turned off.

Wide working temperature range, -20
℃
~ +55
℃
. Good cycle life and discharge performance
at high temperature.

Built-in low temperature heating element, with TBB power supply system, can realize
automatic battery thermal management under low temperature conditions. With external
power supply (mains power, solar energy, vehicle engine), the battery temperature can be
automatically heated to meet the requirements of charging and discharging under low
temperature conditions. It will take about 90 minutes from -20
℃
to +5
℃
.

The battery has small size, light weight and high energy density.

Comply with European RoHS regulations, pass SGS certification, and use non-toxic,
non-polluting environmentally friendly cells.
