Competitor Comparison
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, easy to cause environmental pollution, 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
1. Solar Energy Storage System

Suitable for household and industrial-commercial photovoltaic power stations. It stores photovoltaic power during the day and releases it during peak night hours to achieve "peak shaving and valley filling", reducing electricity costs. It automatically switches to emergency power supply in case of sudden power outages to ensure continuous power supply for key equipment.

2. Off-Grid & Mobile Power Supply

Applicable to off-grid scenarios such as RVs, camping, field exploration and border posts. The lightweight design facilitates carrying and installation. A single charge can meet the long-term power supply needs of multiple devices, replacing traditional diesel generators with green, environmental protection and no noise.

3. Industrial & Backup Power Supply

Can be used as UPS uninterruptible power supply and industrial equipment backup power supply. It features fast response speed and stable power supply, effectively coping with power grid voltage fluctuations and sudden power outages, avoiding losses caused by equipment shutdown. Widely used in data centers, electronic factories, medical equipment and other scenarios.
