105Ah 12V TBB Power Lithium Iron Phosphate Battery with Heating & 200A BMS for

What is the TBB-M12100?

The TBB-M12100 is a high-performance 105Ah 12V Lithium Iron Phosphate (LiFePO₄) battery, designed for superior safety, efficiency, and longevity. This "P" model is the newest generation of the battery featuring a built-in 200A BMS, low-temperature heating function, and parallel expandability. It is an ideal solution for energy storage in vehicles, marine applications, and off-grid power systems.

With an intelligent battery management system (BMS), the TBB-M12100 actively monitors and protects against common battery risks, ensuring stable and reliable operation.

Key Benefits of the TBB-M12100

- Long Cycle Life: Provides up to 3,000 cycles at 25°C, 0.5C charge/discharge rate, far exceeding traditional lead-acid batteries.

- High-Performance BMS: Offers full protection against: Overcharging & over-discharging Over-current & short circuits High & low-temperature operation Cell voltage balancing & cycle life tracking

- High Discharge Capacity: Supports a maximum 200A discharge current for high-power applications.

- Parallel Expandability: Supports up to 8 units in parallel, increasing total capacity to 12V 840Ah.

- Automatic Wake-Up: In shutdown mode, if an external charging voltage >14V is detected, the battery will automatically activate, enabling charging while preventing discharge.

- Optional TBB-MCK Display Panel: Enables battery switch control and real-time monitoring of voltage, current, and State of Charge (SOC).

- Low Power Consumption: <50mA standby consumption when powered on <0.1mA ultra-low standby draw when powered off

- Dry Contact Shutdown Control: Includes a dry contact port that allows users to completely switch off the battery, reducing power consumption to an absolute minimum—ideal for long-term storage or emergency cut-off.

- Bluetooth Monitoring (Optional): Compatible with the TBB-DTU Bluetooth module, enabling wireless monitoring of key battery metrics such as SOC, voltage, current, and alarms through the TBB Battery mobile app ( Google Play or Apple App store)

- Wide Operating Temperature: Functions from -30°C to +60°C, with excellent cycle life and discharge performance even at high temperatures.

- Integrated Low-Temperature Heating: When connected to an external power source (mains, solar, or vehicle engine), the built-in heating function automatically raises the battery temperature to allow safe charging and discharging. Heating from -20°C to +5°C takes approximately 30 minutes.

- Compact & Lightweight: Smaller and lighter than lead-acid alternatives, offering high energy density and space efficiency.
