The LiFePO4 Battery 12V 280Ah is a high-performance lithium iron phosphate battery offering superior energy density, longevity (3,000–5,000 cycles), and safety. Ideal for solar systems, RVs, and marine applications, it operates efficiently in extreme temperatures (-20°C to 60°C) and requires zero maintenance. Its lightweight design and fast charging make it a cost-effective alternative to lead-acid batteries.

How Does LiFePO4 Chemistry Enhance Battery Performance?
LiFePO4 (lithium iron phosphate) chemistry provides thermal stability, reducing combustion risks. It delivers consistent voltage output, even at low charge levels, and resists degradation from deep discharges. With a higher energy density (90–160 Wh/kg) than lead-acid batteries, it ensures longer runtime and faster charging (1-3 hours with compatible chargers).
The crystal structure of lithium iron phosphate inherently resists thermal runaway, a critical safety advantage over other lithium-ion chemistries. This stability allows the battery to maintain 95% capacity retention after 1,000 cycles, compared to nickel-based batteries that typically degrade to 80% within 500 cycles. The flat discharge curve of LiFePO4 ensures devices receive stable voltage until 90% depth of discharge, optimizing performance in applications like solar inverters. Advanced cell balancing through integrated BMS technology further enhances efficiency by preventing individual cell overcharging, which contributes to the battery’s industry-leading 10-year design life.
What Cost Savings Does This Battery Offer Over Time?
Though pricier upfront ($800–$1,200), the LiFePO4 280Ah saves 40–60% over 10 years versus lead-acid. Reduced replacement cycles, zero maintenance costs, and 95% round-trip efficiency (vs. 80% for lead-acid) lower energy waste. Tax incentives for renewable energy systems further offset initial costs.
A detailed cost analysis reveals significant long-term benefits. For example, a lead-acid battery bank requiring 5 replacements over 10 years would cost $4,500+ in purchase and maintenance, while a single LiFePO4 unit costs $1,200 with no replacements. The higher efficiency converts to tangible savings: a 5kW solar system using this battery wastes 125W less per charge cycle than lead-acid equivalents. Commercial users report ROI within 3-4 years through reduced downtime and energy losses. Additionally, the battery’s 100% depth-of-discharge capability effectively doubles usable capacity compared to lead-acid models restricted to 50% DoD.
| Cost Factor | LiFePO4 280Ah | Lead-Acid Equivalent |
|---|---|---|
| 10-Year Replacement Costs | $1,200 | $4,500 |
| Energy Waste (5kW System) | 5% | 20% |
| Maintenance Hours/Year | 0 | 15 |

FAQs
- How long does the 12V 280Ah battery last on a single charge?
- Runtime depends on load: a 500W inverter draws ~42A, providing ~6.6 hours at full load. Lower loads (e.g., 100W fridge) extend runtime to 33 hours.
- Is this battery suitable for cold climates?
- Yes, but charging below 0°C requires a heated model or insulated enclosure to prevent lithium plating. Discharging works down to -20°C.
- Can I replace my lead-acid battery with this LiFePO4 model?
- Yes, but ensure your charger and charge controller are lithium-compatible. Update voltage settings to match LiFePO4 requirements (14.6V absorption, 13.6V float).
