With a massive 5.12kWh energy capacity, this unit provides a lighter, more efficient alternative to traditional AGM battery banks, typically replacing up to 800Ah of lead-acid capacity. ADVANCED THERMAL MANAGEMENT: Equipped with an internal heating mat, this battery automatically regulates its temperature when an external charge source is detected, allowing for safe charging in extreme conditions as low as -20°C. Key Features ✔ 300A Continuous Discharge: Ideal for high-load appliances like A/C and microwaves. ✔ Parallel Expansion: Connect up to 8 units for a total of 3,200Ah capacity. ✔ Smart BMS: Complete protection against over-voltage, short circuits, and heat. ✔ Long Cycle Life: Rated for >3,000 cycles at 100% depth of discharge. Technical Specs Nominal Voltage: 12.8V Rated Capacity: 400Ah Total Energy: 5120 Wh Max Discharge: 300A Continuous Weight: 42.5 kg Dimensions: 462 x 237 x 321 mm Communication: CAN / RS485 Compatibility / Fitment Guide Make/System Model/Application Notes Grand Design RV ELP (Extreme Lithium Package) Direct OEM replacement/upgrade Northwood Mfg FoxForward Systems Integrated power systems Marine Systems Troller/House Bank 12V IP20 rating; internal install only Off-Grid Solar 12V Battery Bank Compatible with TBB and Victron inverters OEM Cross Reference TBB Power PN TBB-M12400 / M12-400 FSi PN FSi-M12-400 (Future Solutions Inc) Regulatory Compliance UN38.3, CE, UN ECE R10.06 Questions & Answers Is this a genuine original part? This is an authentic TBB Power product, supplied by Solarika, providing the highest grade of lithium cell technology for automotive and marine use. How do I know if it is compatible? Check your existing battery label for MPN "M12-400" or the TBB logo. This unit is widely used in Grand Design RVs and premium boat builds. Does it require a specific monitor for the heater to work? No, the heating mat is managed automatically by the internal BMS. When external charging voltage (>14V) is detected in cold environments, the BMS uses that power to heat the cells before initiating charge. Note: Due to shipping regulations for high-capacity lithium batteries (Class 9 Dangerous Goods), please ensure you are available for freight delivery.
