What is the TBB-M12100?

The TBB-M12100 is a high-performance 100Ah 12V Lithium Iron Phosphate (LiFePO₄) battery, designed for superior safety, efficiency, and longevity. 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.
