Chemistry: Lithium Iron Phosphate (LiFePO4) - maintains well-regarded safety, stability, and extended lifespan characteristics.

Voltage: 12V - compatible with most off-grid solar systems and 12V DC appliances.

Capacity: 350Ah (Amp-hours) - exceptional capacity, allowing it to deliver 1 Amp for 350 hours, 5 Amps for 70 hours, or various combinations in between. This makes it suitable for very demanding applications.

Energy Storage: While the listing mentions 4kWh (kilowatt-hours) of energy storage, there seems to be a slight discrepancy. Here's a clarification:

  • The battery's capacity is 350Ah.
  • To calculate actual energy storage in kWh, you multiply the voltage by Ah and then divide by 1000 (conversion factor from Ah to kWh). In this case, it would be:

Energy Storage (kWh) = (12.8V x 350Ah) / 1000 = 4.4 kWh

This 4.2kWh is a more accurate representation of the usable energy storage of this battery.

Benefits of LiFePO4 12V 350Ah Lithium Battery:

  • Unmatched Lifespan: Compared to lead-acid batteries, LiFePO4 boasts a significantly longer lifespan, typically around 6,000 cycles (depending on the depth of discharge).
  • Lightweight Champion: Despite its high capacity, these batteries are considerably lighter than lead-acid batteries of similar capacity, making them relatively portable for applications like RVs and boats.
  • Safety First: The inherent safety features of LiFePO4 chemistry reduce the risk of overheating or explosions compared to lead-acid batteries.
  • Faster Charging: Generally accepts charges faster than lead-acid batteries.
  • Deep Discharge Tolerance: Can be discharged to a greater depth without significantly impacting lifespan compared to lead-acid batteries.


  • Off-grid Solar Systems: Store a significant amount of solar energy to power your entire house or large appliances for extended cloudy or sunless periods. This 4.2kWh capacity can be particularly useful for larger off-grid systems.
  • Large RV and Boat House Battery System: Provides substantial off-grid power for all your appliances and electronics during adventures or outages.
  • Industrial or Commercial Off-Grid Power: Can be used in off-grid applications like remote work sites, cell towers, or mobile medical facilities.
  • High-Demand Portable Power: Ideal for powering professional events, powering film equipment, or other applications requiring significant portable power for extended durations.

Things to Consider When Choosing a LiFePO4 12V 350Ah Battery:

  • Voltage and Capacity: Ensure the 12V voltage matches your system's requirements. The 350Ah capacity is suitable for very demanding applications, but even larger systems might need multiple batteries connected in parallel for even more capacity.
  • Charging System Compatibility: Verify your battery charger is compatible with LiFePO4 chemistry and 12V voltage.
  • Depth of Discharge: While these batteries handle deeper discharge well, avoid routinely draining them completely to maximize lifespan.
  • Weight and Size: While lighter than lead-acid equivalents, the high capacity makes this battery physically larger and heavier than lower-capacity LiFePO4 12V options. Consider weight and available space for installation.
  • Temperature Range: LiFePO4 batteries function well in a wider range of temperatures than lead-acid batteries, but always check the specific model's specifications for optimal operating temperatures.
