3.2v lithium battery
What is a 3.2V Lithium Battery?
A 3.2V lithium battery is a rechargeable battery cell based on Lithium Iron Phosphate (LiFePO4) chemistry, known for its stable voltage platform, high safety, and long cycle life. The nominal voltage of 3.2V makes it an ideal building block for 12V, 24V, and 48V battery pack systems, commonly used in solar energy storage, electric vehicles, UPS systems, and industrial backup power. For OEMs and system integrators, 3.2V LiFePO4 cells provide a reliable, scalable foundation for assembling high-performance energy systems.
Stable Voltage Platform and Extended Lifespan
3.2V lithium batteries are favored for their high thermal and chemical stability, maintaining consistent voltage throughout the discharge cycle. This makes them more efficient and predictable than other lithium chemistries such as NMC or LCO. With a typical cycle life of 2000–6000 cycles, 3.2V LiFePO4 cells offer low degradation and long-term performance—critical for applications that require continuous operation and minimal maintenance. Their low internal resistance also allows for fast charging and high current discharge, without overheating or compromising safety.

3.2V Lithium Battery – Frequently Asked Questions
Can 3.2V lithium batteries be mixed with 3.6V or 3.8V batteries?
No, we do not recommend mixing them. Although the voltages are close, they belong to different chemistries with different charging cutoffs and safety thresholds, which may result in reduced performance or risk of failure.
Do I need a special charger for a 3.2V lithium battery?
Yes. These batteries must be charged with a constant-current/constant-voltage (CC/CV) charger with a 4.2V cut-off to ensure safe and optimal charging.
Can I build a battery pack using multiple 3.2V cells?
Yes. 3.2V cells can be assembled in series or parallel to form a complete battery pack, with BMS protection and optional enclosure customization.
Are 3.2V lithium polymer batteries safe?
Yes. Pouch cells use aluminum-plastic film casings that bulge upon failure, offering visible early warnings. They are thermally stable and comply with international safety standards.
Can I customize the battery size to fit my product?
Absolutely. We offer full customization for size, capacity, voltage, terminals, and protection—ideal for micro-devices or spatially constrained applications.
