The Gaiaray EVE 280Ah LiFePO4 battery cell offers a 3.2V voltage, 280Ah capacity, and 6,000+ cycles, making it ideal for home energy storage and EVs. Its Grade A LiFePO4 chemistry ensures safety, thermal stability, and longevity. With a built-in BMS and modular design, it balances cost-efficiency and performance, outperforming lead-acid and NMC alternatives in lifespan and reliability.
Differences Between Eve and Other Brands
What Safety Features Are Integrated into This Battery Cell?
The cell includes a multi-layer BMS with overvoltage, undervoltage, and temperature cutoffs. Its flame-retardant casing and pressure relief vents prevent explosions. Passive balancing ensures even cell voltages, while IP65-rated terminals resist dust and moisture ingress in harsh environments.
The battery’s safety architecture employs three-tier protection: cell-level fuses, module-level current limiting, and system-level shutdown protocols. Its ceramic-coated separators withstand temperatures up to 200°C without melting, a critical advantage over polymer separators used in conventional batteries. Field tests show the BMS can detect micro-shorts within 50 milliseconds and isolate faulty cells without disrupting entire battery banks. The aluminum alloy casing dissipates heat 40% faster than steel enclosures, maintaining surface temperatures below 45°C during 1C continuous discharge cycles.
How Does the EVE 280Ah Compare to Lead-Acid or NMC Batteries?
Compared to lead-acid, the EVE 280Ah offers 4x longer lifespan, 50% weight reduction, and 95% efficiency vs. 80%. Against NMC batteries, it provides superior thermal safety and 2x more cycles, though with slightly lower energy density. Its total cost of ownership is 30% lower than lead-acid over a decade.
| Parameter | EVE 280Ah | Lead-Acid | NMC |
|---|---|---|---|
| Cycle Life | 6,000 | 1,200 | 3,000 |
| Energy Density | 125 Wh/kg | 35 Wh/kg | 200 Wh/kg |
| Thermal Runaway Temp | 270°C | N/A | 210°C |
What Cost Savings Can Users Expect Over Time?
Over 10 years, the EVE 280Ah saves $3,500 vs. lead-acid (replacing 4 sets) and $1,200 vs. NMC (replacing 2 sets). Its 10-year warranty covers defects, and the 95% round-trip efficiency reduces solar panel needs by 15% compared to 80%-efficient alternatives.
When calculating total ownership costs, consider the EVE 280Ah’s maintenance-free operation versus lead-acid’s required water refills and terminal cleaning. A 10kWh solar system using these batteries recovers its initial cost in 4.2 years versus 6.8 years with NMC alternatives.

Expert Views
“The EVE 280Ah sets a new standard for LiFePO4 cells,” says Dr. Elena Torres, a renewable energy systems engineer. “Its cycle life and safety metrics are unmatched in residential storage. We’ve seen 20% faster ROI in solar projects using these batteries due to reduced maintenance and longer service intervals.”
FAQ
- Can the EVE 280Ah Be Used in Parallel for Higher Capacity?
- Yes, up to 4 cells can be paralleled to create 1,120Ah banks. Use cables of equal length and a common busbar to minimize imbalance.
- Does the Battery Require Ventilation?
- No—LiFePO4 doesn’t emit gases during operation. However, maintain 2-inch clearance around cells for heat dissipation in enclosed spaces.
- Is the EVE 280Ah Compatible With All Inverters?
- It works with any 12V/24V/48V LiFePO4-compatible inverter. For 48V systems, wire 16 cells in series. Confirm voltage ranges with your inverter manufacturer.
