The EVE 3.2V 105AH LiFePO4 battery is a Grade A rechargeable cell designed for solar energy storage. With free busbars, it simplifies DIY configurations for 12V, 24V, or 48V lithium battery packs. Its high energy density, 4,000+ cycle life, and thermal stability make it ideal for off-grid systems, EVs, and backup power. Compared to lead-acid batteries, it offers 50% more usable capacity and faster charging.

How Does the EVE 3.2V 105AH Cell Compare to Other Lithium Batteries?
The EVE LiFePO4 cell outperforms standard lithium-ion (Li-ion) and lead-acid batteries in safety and longevity. Unlike Li-ion, it resists thermal runaway, making it fire-resistant. With a 10-year lifespan under 80% depth of discharge (DoD), it lasts 4x longer than lead-acid. Its flat voltage curve ensures stable power delivery between 3.0V-3.2V, maximizing solar inverter efficiency.
| Parameter | LiFePO4 | Li-ion | Lead-Acid |
|---|---|---|---|
| Energy Density | 90-120 Wh/kg | 150-200 Wh/kg | 30-50 Wh/kg |
| Cycle Life | 4,000+ | 1,000 | 500 |
| Thermal Runaway Risk | None | High | Low |
When considering total cost of ownership, the EVE cell’s 4,000-cycle lifespan translates to $0.03 per cycle for a $120 cell, versus $0.20 per cycle for equivalent lead-acid batteries. This chemistry maintains 95% capacity retention after 2,000 cycles when kept below 35°C, compared to NMC lithium batteries that typically degrade to 80% capacity in the same period. For solar applications requiring daily cycling, this makes LiFePO4 the only viable lithium chemistry for installations with 7+ year ROI timelines.

What Safety Features Does the EVE LiFePO4 Battery Include?
EVE cells integrate three protection layers:
“The multi-stage safety architecture in these cells sets a new industry benchmark. In our stress tests, EVE batteries withstood nail penetration at 100% SOC without combustion – a critical advantage over traditional lithium-ion.” – Battery Safety Lab Report
| Safety Layer | Function | Activation Threshold |
|---|---|---|
| CID | Permanent circuit disconnection | 1.5MPa internal pressure |
| Separator | Dendrite prevention | 140°C shutdown |
| Casing | Flame containment | 800°C for 30 minutes |
The ceramic-coated separators deserve special attention. These 20μm thick membranes feature 0.1μm pores that allow ion flow while physically blocking metallic dendrites. Combined with the CID’s mechanical pressure release mechanism, this dual protection prevents the cascade failures common in aged lithium batteries. For DIY installations, pairing these cells with a UL-listed BMS adds secondary protection against overcurrent (＞150A) and cell imbalance (＞50mV).

What Are the Key Specifications of the EVE 105AH LiFePO4 Battery?
• Nominal voltage: 3.2V ±0.05V
• Capacity: 105Ah @ 0.5C discharge rate
• Energy: 336Wh
• Cycle life: 4,000+ cycles at 80% DoD
• Operating temperature: -20°C to 55°C (charge), -30°C to 60°C (discharge)
• Self-discharge rate: ≤3% per month
• Terminal type: M6 threaded studs
Why Choose LiFePO4 Chemistry for Solar Energy Storage?
LiFePO4 batteries excel in solar applications due to their deep cycling capability and low maintenance. They maintain 80% capacity after 2,000 cycles vs. 500 cycles for AGM batteries. With no liquid electrolytes, they’re vibration-resistant for mobile installations. Their 95% round-trip efficiency outperforms lead-acid’s 80%, capturing more solar energy per day.
How to Build a 12V/24V/48V Battery Pack Using EVE Cells?
- Calculate voltage needs: 4 cells in series (4S) = 12.8V
- Use nickel-plated busbars (included) for low-resistance connections
- Install a BMS (battery management system) rated for 100A continuous
- Compress cells with 300kgf fixture to prevent delamination
- Test voltage balance (±0.02V tolerance)
Can You Use EVE Cells in Extreme Temperatures?
Yes, but with caveats. Charging below 0°C requires a heating blanket to prevent lithium plating. Above 45°C, reduce charge current by 20%. In Arctic conditions, insulation boxes maintain optimal 15-25°C operating range. The cells tolerate -30°C discharge but at reduced 0.3C rate.
What Maintenance Is Required for LiFePO4 Solar Batteries?
LiFePO4 requires minimal maintenance:
• Balance cells annually using a 0.5A active balancer
• Clean terminals with anti-oxidant gel quarterly
• Avoid persistent 100% SoC – store at 50% if unused >1 month
• Update BMS firmware biannually for new protection algorithms
Expert Views
“The EVE 105Ah cell represents a paradigm shift in DIY energy storage,” notes a lithium battery engineer with 12 years’ EV industry experience. “Its 1C continuous discharge (105A) enables compact 5kW systems – previously requiring 8x lead-acid batteries. The included busbars save 15% on pack assembly costs. However, users must invest in a quality BMS; we’ve seen 80% of failures trace to $20 Amazon units.”
- Q: How many cycles will the EVE 105Ah last in daily solar use?
- A: With daily 80% DoD, expect 10+ years (3,650 cycles) before capacity drops to 80%.
- Q: Can I mix EVE cells with other brands in a battery pack?
- A: Not recommended – capacity variances >5% cause BMS balancing failures. Always use same batch cells.
- Q: What’s the maximum continuous current from a single EVE cell?
- A: 105A (1C) continuous, 210A (2C) pulse for 3 seconds. Use 25mm² cables for full current capacity.
