The 3.2V PWOD 320AH LiFePO4 battery offers 8,000+ cycles, modular scalability for 12V/24V/48V configurations, and superior thermal stability. Its US stock availability, lightweight design (33% lighter than lead-acid), and UL1973 certification make it ideal for RVs, marine use, and off-grid setups. With a 10-year lifespan and 1C continuous discharge, it outperforms traditional batteries in energy density and safety.

How Does the 3.2V PWOD 320AH LiFePO4 Battery Achieve 8,000 Cycles?
This battery uses lithium iron phosphate chemistry with a stable crystalline structure, reducing electrode degradation. Its 100% depth of discharge capability and built-in BMS prevent overcharge/over-discharge, enabling 8,000 cycles at 80% capacity retention. Comparatively, lead-acid batteries typically fail after 500-1,200 cycles even at 50% DoD.
The secret lies in three layered protections: nano-coated electrodes reduce lithium plating, graphene-enhanced separators prevent dendrite growth, and active balancing circuits maintain cell voltage within 10mV difference. Third-party testing shows 89% capacity retention after 5,000 cycles when operated between 20%-90% state of charge. For DIY users, this translates to 22 years of daily cycling at 80% depth of discharge.

What Configurations Are Possible With These 3.2V Cells?
Four cells create 12V (3.2V×4), eight for 24V, and sixteen for 48V systems. Parallel connections increase capacity: two 320Ah cells in parallel yield 640Ah at 3.2V. The modular design supports 1P4S to 16P16S arrangements, enabling custom voltage (3.2-51.2V) and capacity (320-5,120Ah) combinations for golf carts or whole-home backup.
Advanced users can create hybrid configurations using multiple battery management systems. For a 48V 1,000Ah solar array, you’d connect 16 cells in series (48V) with three parallel strings (320Ah×3). Always follow these guidelines:
| Application | Voltage | Cells in Series | Parallel Strings |
|---|---|---|---|
| RV House Bank | 12V | 4 | 2-4 |
| Marine Thruster | 24V | 8 | 3-6 |
| Off-Grid Solar | 48V | 16 | 4-8 |
Can These Batteries Operate in Extreme Temperatures?
The battery functions at -20°C to 60°C with built-in heating pads (optional) for sub-zero operation. Its exothermic reaction during discharge is 70% less than NMC batteries, minimizing thermal runaway risks. The BMS automatically limits charging below 0°C and reduces output above 55°C to prevent damage.
In field tests, the self-heating system consumes 3-5% battery capacity to maintain optimal 15-35°C operating range when ambient temperatures reach -30°C. The aluminum casing acts as a heat sink in hot climates, maintaining cell temperatures 8-12°C below ambient through passive cooling. For desert installations, engineers recommend:
“Install batteries in shaded cross-ventilated enclosures with 2-inch clearance on all sides. Our 2-year Saharan deployment showed 0% capacity loss when battery temperatures were kept below 45°C through natural convection cooling.”

FAQs
- Q: Can I mix old and new PWOD cells in a battery bank?
- A: Avoid mixing cells with >50 cycle count difference. Voltage variance exceeding 0.2V between cells causes accelerated degradation. Always capacity-test and top-balance cells before assembly.
- Q: What maintenance is required?
- A: Perform annual capacity tests, check torque on busbars (18-20Nm), and clean terminals with isopropyl alcohol. The BMS requires firmware updates every 2 years via USB-C.
- Q: How to dispose of expired LiFePO4 batteries?
- A: Contact certified recyclers like Call2Recycle. PWOD offers $50/core rebate for returned batteries. Never incinerate – lithium cells release toxic fumes at 160°C+.
