What Are the Key Specifications of the Gaiaray 3.2V 320Ah LiFePO4 Battery?
The battery features a nominal voltage of 3.2V and capacity of 320Ah, with a 48V configuration achieved through series connections. It offers 6,000–8,000 deep cycles at 80% DoD, 95% round-trip efficiency, and a 10-year design lifespan. Built-in BMS protects against overvoltage, short circuits, and thermal runaway, ensuring compliance with UL1973 and UN38.3 certifications.
How Does LiFePO4 Chemistry Benefit Solar Energy Storage?
LiFePO4 batteries excel in solar applications due to their thermal stability, minimal capacity degradation, and high charge/discharge rates. The Gaiaray model maintains 90% capacity after 4,000 cycles, enabling daily solar charging without performance drops. Its flat discharge curve ensures consistent voltage output, critical for powering inverters during peak household energy demands.

What Safety Features Protect the Gaiaray LiFePO4 Battery?
Multi-layered safeguards include:
- Cell-level voltage/temperature monitoring
- Automatic load disconnection during 2.5V undervoltage or 3.65V overvoltage
- IP65-rated casing resisting dust/water ingress
- Flame-retardant electrolytes (UL94 V-0 certification)
- Pressure relief vents preventing gas accumulation
These features enable safe operation in garages, sheds, or outdoor solar installations. The IP65 rating ensures protection against harsh weather conditions, while the cell-level monitoring system provides real-time diagnostics. Unlike traditional systems, the pressure relief vents actively manage internal gas pressures during extreme temperatures, eliminating explosion risks. The UL94 V-0 certification confirms the battery casing self-extinguishes flames within seconds, a critical advantage for enclosed installations.
How Does It Compare to Traditional Lead-Acid Batteries?
| Metric | Gaiaray LiFePO4 | Lead-Acid |
|---|---|---|
| Cycle Life | 6,000+ | 500–1,200 |
| DoD | 80% | 50% |
| Efficiency | 95% | 80–85% |
| Weight | 15.4 lbs | 55–70 lbs |
| Maintenance | None | Monthly |
This comparison highlights why LiFePO4 technology dominates modern energy storage. The 80% usable capacity effectively doubles the functional energy availability compared to lead-acid alternatives. At 1/4 the weight, these batteries simplify installation in attic spaces or wall-mounted racks. The elimination of electrolyte top-ups and terminal cleaning reduces long-term ownership costs by approximately 40% according to industry studies.
What Is the Optimal Charging Protocol for Maximum Lifespan?
Charge at 0.5C (160A) with CC/CV method:
- Bulk Charge: 3.65V/cell at 160A until 90% SoC
- Absorption: Hold 3.65V until current drops to 0.05C (16A)
- Float: Maintain 3.4V/cell
Avoid continuous charging above 45°C. Use MPPT solar controllers with LiFePO4 profiles to prevent voltage spikes.
Expert Views
“Gaiaray’s cell balancing algorithm is industry-leading. Most LiFePO4 batteries lose 3-5% capacity annually from cell drift, but their active equalization maintains ±10mV variance even after 2,000 cycles. For off-grid installations, this translates to 15% more usable energy over a decade compared to budget alternatives.”
