TBB-M12200 — 12.8V 200Ah LiFePO₄ Battery with 300A BMS & Low-Temp Heating
A high-performance 12.8V (2.56 kWh) lithium iron phosphate battery from TBB Mobile, built for off-grid power, marine and vehicle systems. Features an integrated 300A BMS, optional Bluetooth, low-temperature heating, and parallel expandability up to 8 units.
2.56 kWh @ 12.8V 300A Smart BMS Low-Temp Heating Up to 8 in Parallel 5-Year Warranty
Why choose the TBB-M12200
- Long service life — up to 3,000 cycles at 100% DoD (25 °C, 0.5C charge/discharge), far outlasting lead-acid.
- 300A high-performance BMS — protects against over/under-voltage, over-current, short circuit, and temperature extremes with cell balancing for maximum life.
- High discharge capability — 200A continuous, up to 300A for 10 minutes to support heavy loads.
- Parallel expandability — connect up to 8 batteries in parallel for larger systems.
- Low-temperature heating — integrated heater automatically warms the battery from −20 °C to +5 °C (≈90 mins, uses external power) to enable safe charging in cold climates.
- Automatic wake-up — in shutdown, applies charge automatically when external voltage >14 V is detected.
- Ultra-low standby draw — <50 mA when on; <0.1 mA when off. Dry-contact power-off port allows full shutdown for storage or emergency isolation.
- Monitoring options — optional TBB-DTU Bluetooth dongle + app (iOS/Android) and optional TBB-MCK display for live SOC, voltage, current and system status.
- Compact & lightweight — 25.5 kg with high energy density to save space and weight.
- Wide operating window — reliable performance from −30 °C to +60 C (discharge).
Ideal applications
- Campervans, motorhomes & 4×4 builds
- Marine & narrowboat DC systems
- Off-grid cabins, sheds & mobile workshops
- UPS/backup power with high surge loads
Layered protection & safety
The integrated BMS provides multi-layer protection:
- Short-circuit & 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 over-voltage protection
Monitoring & control (optional)
- TBB-MCK panel — front-of-system display/control for SOC, voltage, current and system status.
- TBB-DTU Bluetooth module — wireless monitoring of SOC, voltage, current and alarms via the TBB Battery app (iOS/Android).

Installer notes
- This model is designed for 12.8 V systems; expand capacity by adding batteries in parallel only (series connection is not supported unless explicitly stated by the manufacturer).
- For cold-weather charging, ensure the low-temperature heating feature is powered and allow time to pre-warm before charging.
- Use appropriately rated cabling, fusing and DC protection for the specified currents. Always follow the inverter/charger manufacturer’s settings for LiFePO₄.
- For long-term storage, use the dry-contact power-off function to fully shut down and minimise idle draw.
