What is the TBB-M12200?

The TBB-M12200 is a high-performance 200Ah 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, parallel expandability, and advanced control options, it’s an ideal solution for off-grid power, marine applications, and vehicle energy systems.

With its intelligent Battery Management System (BMS), the TBB-M12200 actively monitors, protects, and optimises battery performance, ensuring reliable operation and an extended service life.

 

Key Benefits of the TBB-M12200

  • Long Cycle Life: Provides up to 3,000 cycles at 25°C, 0.5C charge/discharge rate, vastly outlasting traditional lead-acid batteries.
  • High-Performance BMS: Offers full protection from:
    • Overcharging & over-discharging
    • Over-current & short circuits
    • High & low temperature extremes
    • Cell voltage balancing & cycle life optimisation
  • High Discharge Capability: Supports up to 300A discharge for high-power loads.
  • Parallel Expandability: Connect up to 8 units in parallel for large-scale energy storage.
  • Automatic Wake-Up Function: In shutdown mode, the battery auto-activates when an external charging voltage >14V is applied, allowing charging without discharging.
  • Optional TBB-MCK Display Panel: Enables system control and live monitoring of battery voltage, current, SOC, and system status.
  • Low Power Consumption:
    • <50mA in standby mode when powered on
    • <0.1mA ultra-low standby draw when powered off
  • Dry Contact Power-Off Function: The integrated dry contact port allows the battery to be completely powered down, minimising idle energy use and ideal for long-term storage or emergency power isolation.
  • 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: Reliable performance from -30°C to +60°C.
  • Integrated Low-Temperature Heating: Automatically warms the battery from -20°C to +5°C (approx. 90 minutes) using external power, ensuring safe operation in cold environments.
  • Compact & Lightweight: High energy density reduces weight and saves valuable installation space compared to bulky lead-acid units.

 

Advanced Protection Features

The TBB-M12200 integrates robust multi-layer safety systems for maximum reliability:

  • Short Circuit Protection
  • Over-Current Protection
  • Battery High/Low Voltage Protection
  • Individual Cell High/Low Voltage Protection
  • Charge/Discharge Temperature Protection
  • BMS Circuit Over-Temperature Protection
  • External Input Overvoltage Protection

 

Whether you're powering a marine vessel, off-grid cabin, or mobile workspace, the TBB-M12200 delivers superior energy storage with safety, intelligence, and flexibility built in.
