High-capacity 12V platform
12V 300Ah LiFePO4 Battery
A 3.84kWh deep-cycle reference platform for larger RV house-power banks, 12V off-grid auxiliary systems and other applications where more stored energy is required without moving to a 24V architecture.
Ask for the current data sheet, sample terms and final configuration before purchase.

Where it fits
More energy for systems that remain intentionally 12V.
This platform is a practical B2B conversation starter where an end user needs longer RV autonomy or a larger 12V solar reserve. The sales process should carefully distinguish stored energy from power capability: a 3.84kWh battery still has defined continuous and peak current limits.
- RV & camper: larger house-power storage with appliance and inverter loads documented.
- Off-grid auxiliary: 12V solar storage where wiring and controller limits have been reviewed.
- Private label: use final artwork, manuals and packaging only after the approved configuration is locked.
Buyer FAQ
Qualifying a 12V 300Ah project
How is nominal energy calculated?
Nominal energy is voltage multiplied by capacity: 12.8V × 300Ah = 3,840Wh or 3.84kWh. Actual usable energy varies with the load, temperature, system cut-offs and operating conditions.
Can I connect multiple 300Ah units?
The current product specification permits four matched modules in series and four in parallel. Use only approved, same-batch modules and a documented system design. Connection capability does not remove the need to manage each system's current, fusing and cable sizing.
Can it run a high-power inverter?
Begin with the inverter's sustained DC current and surge profile, not the inverter's headline AC wattage. The source specification lists 150A maximum continuous discharge and 180A peak for 1 second; an engineering review should determine suitability.
Does Bluetooth replace installation checks?
No. Bluetooth monitoring can support visibility but does not replace the required installation, electrical protection, charging and compliance review.
Plan for the whole system
