The GradeA+ EVE 280Ah LiFePO4 battery delivers exceptional performance through advanced engineering. Its lithium iron phosphate chemistry ensures thermal stability even under heavy loads, while modular design allows flexible capacity expansion across residential and commercial installations.
What Are the Key Applications of the EVE 280Ah Battery?
This battery is ideal for solar energy storage, marine/RV systems, off-grid power, and emergency backups. Its 12V/24V/48V configurations support scalability for residential and commercial setups. With a 3.2V nominal voltage per cell, it integrates seamlessly with inverters like Victron and SMA, delivering 280Ah-320Ah capacity for sustained high-current demands.
For solar installations, the battery’s 98% round-trip efficiency minimizes energy loss during daily charge/discharge cycles. Marine applications benefit from its vibration-resistant structure, with optional IP65 enclosures protecting against saltwater corrosion. In off-grid cabins, four 280Ah cells wired in series can store 14.3kWh – enough to power essential appliances for 24-48 hours without sunlight. Commercial users often deploy rack-mounted configurations of 16 cells (51.2V system) to achieve 89.6kWh storage capacity, scalable through parallel connections.

How Does the 314Ah/320Ah Upgrade Enhance Performance?
The 314Ah/320Ah variants use thickened electrodes and enhanced electrolyte formulas, boosting energy density to 170Wh/kg. This upgrade extends runtime by 12-15% while maintaining the same footprint. Ideal for high-load applications like electric vehicles or industrial UPS systems, these cells support 1C continuous discharge without capacity fade.
The upgraded cells feature nickel-plated aluminum busbars that reduce internal resistance to 0.15mΩ per cell, enabling 400A peak discharge currents. For electric vehicle conversions, this means improved acceleration and hill-climbing capability. Industrial users benefit from the 320Ah model’s -30°C low-temperature charging capability using proprietary electrolyte additives. Testing shows 91% capacity retention after 2,000 cycles at 100% DoD in UPS applications, significantly outperforming standard lead-acid alternatives.
| Model | Energy Density | Cycle Life @100% DoD | Low-Temp Charge |
|---|---|---|---|
| 280Ah | 155Wh/kg | 3,500 cycles | -20°C |
| 320Ah | 170Wh/kg | 4,200 cycles | -30°C |
Which Safety Features Protect the EVE LiFePO4 Battery?
EVE’s LiFePO4 cells are non-flammable, passing nail penetration and crush tests per UN38.3 standards. The built-in BMS enforces temperature monitoring (-20°C to 60°C), short-circuit protection, and cell balancing. Thermal runaway prevention and IP65-rated enclosures (optional) make it safe for humid or dusty environments.
Why Choose EU Tax-Free EVE Batteries for Solar Systems?
GradeA+ EVE batteries shipped to the EU bypass 22% VAT and customs duties under TARIC code 85076000. Direct-from-factory pricing cuts middleman costs, saving 30-40% versus retail brands. Pre-installed EU compliance certificates (CE, RoHS) ensure hassle-free import for solar installers and DIY enthusiasts.
Expert Views
