The Grade A 8000 Cycle 320Ah Lifepo4 Battery is a lithium iron phosphate (LiFePO4) cell optimized for longevity, safety, and high energy density. With 8000 charge cycles at 80% depth of discharge (DoD), it outperforms traditional lead-acid batteries. Its 3.2V design allows seamless integration into 12V/24V systems for RVs, solar setups, and off-grid applications, backed by EU stock availability for faster delivery.
What Is a DC to DC Lithium Battery Charger and How Does It Work
How Does the 8000-Cycle Lifespan Compare to Other Batteries?
LiFePO4 batteries typically offer 2000-5000 cycles, but this Grade A cell achieves 8000 cycles due to advanced electrode coatings and thermal stability. Lead-acid batteries last 300-500 cycles, making the 320Ah LiFePO4 16x more durable. Key factors enabling longevity include:
- Stable lithium iron phosphate chemistry resisting dendrite formation.
- Built-in Battery Management System (BMS) preventing overcharge/over-discharge.
- Low self-discharge rate (3% monthly vs. 30% for lead-acid).
To contextualize the 8000-cycle claim, consider a solar camping scenario with daily charging. At one full cycle per day, this battery would last over 21 years before reaching 80% capacity. Even with heavier use (2 cycles daily), it maintains over a decade of reliable service. Comparatively, a lead-acid battery would require replacement every 4-8 months under similar conditions. The table below illustrates key differences:
| Battery Type | Cycle Life | Energy Density (Wh/kg) | Weight (320Ah Equivalent) |
|---|---|---|---|
| LiFePO4 (Grade A) | 8000 | 120-140 | 5.8kg |
| Standard LiFePO4 | 3000 | 90-110 | 7.2kg |
| Lead-Acid | 500 | 30-50 | 21kg |
What Safety Features Are Integrated into This Battery?
Unlike lithium-ion variants, LiFePO4 chemistry is inherently non-combustible. Additional safeguards:
- Multi-layer separator preventing internal short circuits.
- Flame-retardant casing (UL94 V-0 certification).
- BMS with temperature sensors (-20°C to 60°C operational range).
- Overcurrent protection (200A peak, 100A continuous).
DEESPAEK Lithium Iron Phosphate (LiFePO4) Battery
The battery’s thermal runaway threshold is 270°C – significantly higher than the 150°C typical of NMC cells. This makes it ideal for enclosed spaces like RVs or marine cabins. The BMS actively monitors cell balancing, ensuring no single cell exceeds 3.65V during charging or drops below 2.5V during discharge. In stress tests, these cells withstand nail penetration without combustion, unlike traditional lithium-ion batteries. For users in fire-regulated areas or extreme climates, these certifications and safeguards provide critical peace of mind.
Which Applications Benefit Most from the 320Ah LiFePO4 Cell?
Ideal applications include:
- Solar Energy Storage: Stores 1024Wh per cell (3.2V x 320Ah), scalable for residential/commercial use.
- RV/Camping Power: Supports 12V/24V systems for inverters, lights, and appliances without voltage sag.
- Marine Use: Water-resistant design handles humid environments.
- EV Conversions: High discharge rate (1C continuous) suits electric vehicles.
How to DIY a 12V/24V System Using 3.2V Cells?
For a 12V system:
- Connect 4 cells in series (4 x 3.2V = 12.8V).
- Attach a 12V BMS balancing charge/discharge.
For 24V:
- Link 8 cells in series (8 x 3.2V = 25.6V).
- Use a 24V BMS. Ensure busbars are rated for 200A+ to handle peak loads.
Are There Certifications Supporting This Battery’s Reliability?
Certifications include:
- UN38.3 (transport safety).
- IEC 62619 (industrial applications).
- CE/RoHS (EU compliance).
- ISO 9001 manufacturing standards.
“The 320Ah LiFePO4 cell represents a paradigm shift in energy storage. Its cycle life reduces replacement frequency, while the modular design lets users scale systems cost-effectively. For DIY enthusiasts, it’s a game-changer—no more wrestling with bulky lead-acid batteries.”
