TBB Power 400Ah 12V TBB Power Lithium Iron Phosphate Battery with Heating & 300A BMS for Leisure, So

Product Description

What is the TBB-M12400?

The TBB-M12400 is a high-performance 400Ah 12V Lithium Iron Phosphate (LiFePO4) battery, designed by TBB Mobile for safe, efficient, and long-lasting energy storage. Featuring a built-in 300A BMS, low-temperature heating function, and parallel expandability, it is an ideal solution for off-grid power, marine applications, and vehicle energy storage.

With its intelligent battery management system (BMS), the TBB-M12400 actively monitors, protects, and optimizes battery performance, ensuring stable operation and extended lifespan.

Key Benefits of the TBB-M12400


Long Cycle Life: Up to 3,000 cycles at 25°C, 0.5C charge/discharge rate, far surpassing traditional lead-acid batteries.
High-Performance BMS: Provides comprehensive protection, including:

Overcharging & over-discharging
Over-current & short circuits
High & low-temperature protection
Cell balancing & cycle life tracking


High Discharge Capacity: Supports a maximum 300A discharge current for high-power applications.
Parallel Expandability: Supports up to 8 units in parallel, increasing total capacity for large-scale energy storage.
Automatic Wake-Up Function: When an external charging voltage >14V is detected in shutdown mode, the battery automatically activates, allowing charging while preventing discharge.
Optional MEH-B Display Panel: By connecting the optional TBB-MCK remote meter to the battery, this enables extra monitoring and control features such as battery switch control and real-time monitoring of voltage, current, and State of Charge (SOC).
Low Power Consumption:

<50mA standby power consumption when active
<0.1mA ultra-low standby draw when powered off


Wide Operating Temperature: Functions in extreme conditions from -30°C to +60°C, ensuring reliable performance.
Integrated Low-Temperature Heating: When connected to an external power source (mains, solar, or vehicle engine), the built-in heating system automatically raises battery temperature for safe charging and discharging. Heating from -20°C to +5°C takes approximately 90 minutes.
Compact & Lightweight: Offers high energy density, reducing weight and saving space compared to lead-acid alternatives.
