Performance Comparison vs. Lead-Acid Batteries
| Comparison Item | EVE LF334 334Ah LiFePO4 Battery | Ordinary Lead-Acid Battery (Same Capacity Class) |
|---|---|---|
| Cycle Life | ≥6000 cycles, service life 8-10 years | 300-500 cycles, service life 1-2 years |
| Energy Density & Weight | 190Wh/kg, only 5.8kg, compact size | 30-50Wh/kg, about 18kg, bulky size |
| Usage Cost | One-time investment, no replacement for 10 years, low total cost | 2-3 replacements per year, total cost 30%+ higher in 10 years |
| Environmental Protection | No heavy metals, no pollution during production and after disposal | Contains lead and sulfuric acid, environmental pollution risk, difficult to recycle |
| Low Temperature Performance | Maintains over 80% capacity at -20℃ | Capacity drops sharply to below 60% at -20℃, unable to work normally |
| Maintenance Requirement | Maintenance-free, low self-discharge rate, no water replenishment needed | Regular water replenishment and inspection required, cumbersome maintenance |
| Safety | No fire in puncture test, complete overcharge and over-discharge protection | No explosion risk, but prone to leakage and equipment corrosion |
Application Scenarios
- Solar Energy Storage System: Suitable for household and industrial-commercial photovoltaic power stations. Stores photovoltaic power during the day and releases it during peak night hours for "peak shaving and valley filling," reducing electricity costs. Automatically switches to emergency power supply during power outages to ensure continuous operation of critical equipment.
- Off-Grid & Mobile Power Supply: Ideal for RVs, camping, field exploration, and border posts. Lightweight design facilitates transportation and installation. Single charge provides long-term power for multiple devices, replacing traditional diesel generators with green, quiet operation.
- Industrial & Backup Power Supply: Functions as UPS uninterruptible power supply and industrial equipment backup. Features fast response and stable power output, effectively handling grid voltage fluctuations and sudden outages to prevent equipment shutdown losses. Widely used in data centers, electronic factories, and medical equipment applications.
