The Gaiaray LF50F EVE 50Ah Lifepo4 battery is a Grade A lithium iron phosphate (LiFePO4) cell designed for solar energy storage, EVs, and industrial applications. With a 3.2V voltage, 50Ah capacity, and 5,000+ cycle life, it offers high safety, thermal stability, and cost efficiency. Its compatibility with solar systems and low self-discharge rate make it ideal for renewable energy projects.
What Are the Key Specifications of the Gaiaray LF50F Battery Cell?
The LF50F cell operates at 3.2V with a 50Ah capacity, delivering 160Wh of energy. It supports continuous discharge currents up to 50A and peak currents of 150A. Its operating temperature ranges from -20°C to 60°C, and it weighs 1.4kg. The LiFePO4 chemistry ensures non-toxic materials, UL1642 certification, and a lifespan exceeding 10 years under 80% depth of discharge (DoD).
How Does the LF50F Compare to Other Lithium-Ion Batteries?
Unlike traditional NMC or LCO batteries, the LF50F’s LiFePO4 chemistry eliminates thermal runaway risks. It provides 2-3x longer cycle life than standard lithium-ion cells and maintains 80% capacity after 5,000 cycles. Its flat discharge curve ensures stable voltage output, while its higher energy density (140Wh/kg) outperforms lead-acid alternatives by 300%.
When evaluating energy storage options, the LF50F’s advantages become particularly evident in long-term applications. For instance, in solar installations where daily cycling is required, the LF50F’s 5000-cycle lifespan translates to over 13 years of service compared to just 3-5 years for typical lead-acid batteries. This longevity drastically reduces replacement costs and system downtime. Additionally, the battery’s ability to maintain stable voltage under varying loads ensures consistent performance for sensitive electronic equipment.
| Feature | LF50F LiFePO4 | NMC Battery | Lead-Acid |
|---|---|---|---|
| Cycle Life | 5000+ | 2000 | 500 |
| Energy Density (Wh/kg) | 140 | 180 | 40 |
| Thermal Runaway Risk | None | Moderate | Low |
Why Choose LiFePO4 Chemistry for Solar Energy Storage?
LiFePO4 batteries excel in solar applications due to their deep-cycle capability, low self-discharge (3% monthly), and resistance to high temperatures. They charge efficiently at partial states, reducing solar array sizing needs. The LF50F’s 95% round-trip efficiency minimizes energy loss, making it 40% more effective than lead-acid systems over a decade.
What Safety Features Does the Gaiaray LF50F Include?
The cell integrates overcharge/discharge protection, short-circuit prevention, and flame-retardant casing. Its built-in Battery Management System (BMS) monitors temperature, voltage, and current. EVE’s proprietary SEI layer stabilizes the electrolyte, preventing dendrite formation. UL and UN38.3 certifications validate its compliance with transportation and operational safety standards.
The LF50F’s multi-layered safety approach addresses both operational and emergency scenarios. The battery management system (BMS) continuously tracks individual cell voltages, preventing any single cell from overcharging during solar absorption phases. In cold climates, the BMS automatically limits charging currents when temperatures drop below 0°C to prevent lithium plating. The cell’s aluminum alloy casing acts as a heat sink, dissipating thermal energy 40% faster than standard steel enclosures during high-load situations.
| Safety Feature | Function |
|---|---|
| Overcharge Protection | Halts charging at 3.65V/cell |
| Thermal Sensors | Adjust charge rates based on temperature |
| Flame-Retardant Case | Contains internal fires for 30+ minutes |
How to Maintain the LF50F for Optimal Performance?
Store the battery at 50% charge in temperatures below 45°C. Avoid discharging below 2.5V or charging above 3.65V. Balance cells every 6 months using a passive balancing BMS. Clean terminals quarterly to prevent corrosion. Recalibrate the SOC indicator annually by performing a full discharge/charge cycle.
What Are the Environmental Benefits of Using LiFePO4 Cells?
The LF50F contains no cobalt or heavy metals, reducing mining impacts. Its 10+ year lifespan decreases replacement waste by 70% compared to lead-acid. EVE’s closed-loop recycling program recovers 98% of lithium, and the cell’s 99% efficiency lowers CO2 emissions by 12 tons over its lifetime versus diesel generators.
