What Are the Key Specifications of the 320Ah LiFePO4 Cell?
This 3.2V cell delivers 320Ah capacity (1024Wh), operates between -20°C to 60°C, and supports up to 1C continuous discharge. With a built-in Battery Management System (BMS), it prevents overcharge, over-discharge, and short circuits. Its modular design allows easy stacking for 12V, 24V, or 48V configurations, suiting DIY solar projects, marine applications, and camping setups.
| Parameter | Value |
|---|---|
| Nominal Voltage | 3.2V |
| Capacity | 320Ah |
| Energy | 1024Wh |
| Cycle Life | 8000 cycles @ 80% DoD |
| Charge Temperature | 0°C to 45°C |
The cell’s wide operating temperature range makes it suitable for harsh environments, such as desert solar installations or alpine RV trips. Its 1C discharge capability allows rapid energy release for high-power appliances like air conditioners or microwaves. The modular design simplifies system upgrades—users can add parallel cells to increase capacity without replacing existing units. For marine applications, the IP65-rated casing provides resistance to moisture and salt spray.

Why Choose LiFePO4 Over Other Lithium-Ion Chemistries?
LiFePO4 batteries outperform NMC or LCO variants in thermal stability, cycle life, and safety. They resist combustion risks during overcharging or physical damage and operate efficiently in extreme temperatures. Unlike lead-acid batteries, they maintain 90% capacity after 2000 cycles and charge 3x faster, reducing downtime in solar/RV applications.
| Chemistry | Cycle Life | Thermal Runaway Risk |
|---|---|---|
| LiFePO4 | 8000 cycles | Low |
| NMC | 2000 cycles | Moderate |
| Lead-Acid | 500 cycles | High (sulfation) |
LiFePO4’s olivine crystal structure provides inherent stability, eliminating the risk of oxygen release during thermal stress. This chemistry also tolerates partial state-of-charge (PSOC) operation better than lead-acid, making it ideal for solar systems with variable charging patterns. For RV users, the absence of off-gassing allows safe indoor installation, unlike vented lead-acid batteries.
How to Safely Install a DIY 48V LiFePO4 Battery Bank?
Use 16 cells in series for a 48V system. Balance cell voltages before assembly, integrate a BMS for voltage/current monitoring, and secure connections with insulated busbars. Install in a well-ventilated, moisture-free area. Test the system at 50% load initially to validate stability. Always follow manufacturer torque specifications for terminal screws to prevent arcing.
What Maintenance Practices Extend Battery Lifespan?
Avoid discharging below 10% SOC, store at 50% charge in cool environments, and clean terminals quarterly to prevent corrosion. Rebalance cells annually if voltage deviations exceed 0.2V. Use a compatible LiFePO4 charger to avoid overvoltage stress. Most BMS units auto-manage cell balancing, but manual checks ensure optimal performance.
“The Grade A 320Ah LiFePO4 cell redefines energy density and safety for DIY applications. Its 8000-cycle rating isn’t just marketing—third-party tests confirm 85% capacity retention after 6000 cycles. For off-grid systems, this translates to decades of service with minimal upkeep.”

FAQ
- Q: Can this battery power a 5000W inverter?
- A: Yes. A 48V bank (16 cells) provides 15.36kWh capacity, supporting 5000W inverters at 104A continuous draw.
- Q: Is a BMS mandatory for LiFePO4 systems?
- A: Critical. The BMS prevents cell imbalance, overvoltage, and thermal runaway, ensuring safety and longevity.
- Q: How does temperature affect performance?
- A: Below -20°C, charging is disabled to prevent plating. Above 60°C, the BMS throttles discharge rates to protect cells.
