Frequently Asked Questions
1. What is the expected lifespan of these LiFePO4 cells?
These high-quality cells are rated for over 6000 deep discharge cycles before reaching 80% of their original capacity, ensuring long-term reliability for energy storage systems.
2. Are these batteries safe for indoor residential use?
Yes, LiFePO4 (Lithium Iron Phosphate) is widely recognized as one of the safest lithium battery chemistries. It has excellent thermal stability and is significantly less prone to overheating compared to other lithium-ion types.
3. Can I use these cells to build a 12V, 24V, or 48V battery pack?
Absolutely. These 3.2V prismatic cells are designed to be connected in series and parallel to create various pack voltages and capacities suitable for RVs, marine, and home solar backups.
4. What is the internal resistance of the 280Ah cell?
The internal resistance is extremely low, verified at ≤0.25mΩ. This ensures high efficiency and minimal heat generation during high-current charging and discharging.
5. What are the recommended temperature ranges for operation?
For charging, the environment should be between 0°C and 55°C. For discharging, the cells can operate in temperatures ranging from -20°C to 55°C.
6. Do the cells come with a warranty or quality guarantee?
All cells undergo strict testing for capacity, voltage, and internal resistance to ensure they are Grade A and perfectly matched before shipment.
