The Neue 3.2V LiFePO4 320Ah battery is a rechargeable lithium iron phosphate cell designed for DIY energy systems like solar setups, RVs, and marine applications. With high cycle life (4,000+ cycles), thermal stability, and compatibility with 12V/24V/48V configurations, it provides reliable, long-term power storage. Its modular design allows flexible scalability, making it ideal for off-grid and mobile energy solutions.
What Are the Key Applications for This 320Ah Battery?
This battery is optimized for RV solar systems, marine power (boats/yachts), golf carts, and off-grid cabins. Its high capacity supports energy-intensive devices like inverters, air conditioners, and electric vehicles. Modular setups enable 12V (4 cells), 24V (8 cells), or 48V (16 cells) configurations, adapting to voltage demands across residential and mobile applications.
For marine applications, the battery’s waterproof casing and resistance to saltwater corrosion make it ideal for powering navigation systems, bilge pumps, and onboard appliances. In RVs, its compact size (typically 207mm x 174mm x 72mm per cell) allows efficient space utilization while supporting extended boondocking capabilities. Off-grid solar installations benefit from the battery’s 98% round-trip efficiency, which maximizes energy harvest from solar panels. The table below compares typical configurations:

What Maintenance Practices Prolong Battery Lifespan?
Avoid discharging below 10% SOC (2.5V/cell) and store at 50% charge in dry, 15-25°C environments. Use a LiFePO4-compatible charger (3.65V/cell absorption voltage). Rebalance cells annually using a top-balancing BMS. Inspect terminals quarterly for corrosion and tighten connections to prevent voltage drop.
Implement a three-stage maintenance protocol: monthly voltage checks (±0.05V tolerance between cells), seasonal terminal cleaning with anti-oxidant gel, and annual capacity testing using a constant current discharge analyzer. For long-term storage, maintain a 3.3V/cell resting voltage and avoid stacking cells directly on concrete floors. Temperature management is critical – install battery banks in ventilated enclosures with thermal pads to maintain optimal 20-30°C operating ranges. The following maintenance schedule optimizes performance:
| Interval | Action | Tools Required |
|---|---|---|
| Monthly | Voltage balance check | Digital multimeter |
| Quarterly | Terminal torque verification | Torque wrench (4-5Nm) |
| Annually | Full capacity test | Battery analyzer |
Why Choose LiFePO4 Over Lead-Acid or Other Lithium Batteries?
LiFePO4 batteries outperform lead-acid in cycle life (4x longer), depth of discharge (90% vs. 50%), and weight (70% lighter). Unlike NMC lithium batteries, they resist combustion and maintain capacity below 0°C. The 320Ah cell’s 10,000+ cycle lifespan reduces long-term replacement costs, making it cost-effective despite higher upfront investment.
How to Safely Install and Configure a DIY Battery Bank?
Use nickel-plated busbars to connect cells in series/parallel, ensuring uniform torque (4-5 Nm). Integrate a battery management system (BMS) to monitor voltage, temperature, and cell balancing. For 48V systems, stack 16 cells vertically with compression fixtures (300-500 kgf). Test configurations with a multimeter before connecting inverters or solar charge controllers.
“The EVE 320Ah cell’s 1C continuous discharge rating lets it power 5kW inverters without derating—a game-changer for off-grid systems. However, DIY builders must prioritize cell matching; even 10mV differences in open-circuit voltage can cause imbalance in 48V stacks. Always batch-test cells before assembly.” — Renewable Energy Systems Engineer
