How to Select a 3.2V LiFePO4 Battery
Capacity Selection
Estimate based on device power consumption and standby time, with at least 20% capacity margin. High pulse or continuous load applications should also consider discharge rate capability.
Size & Terminals
Available formats include cylindrical (26650, 32650), prismatic, and pouch cells. Output options include tabs, wires, or connectors depending on integration needs.
Battery Protection (BMS)
Standalone 1S multi-parallel packs: BMS recommended for overcharge/over-discharge protection
Multi-series systems: centralized BMS may manage overall protection
Temperature Adaptation
Standard cells operate from -20°C to 60°C. For cold environments, low-temperature formulations are recommended to maintain stable capacity and voltage performance.
Certification Requirements
We support UN38.3, CB, UL and other certifications. Early confirmation helps shorten certification lead time.

3.2V LiFePO4 Lithium Battery FAQs
Can 3.2V LiFePO4 batteries be customized?
Yes. Capacity, discharge rate, structure, and interfaces can all be customized to match your system requirements.
Cylindrical vs pouch cells – how to choose?
Cylindrical cells: high consistency, strong mechanical stability, ideal for industrial/vibration environments
Pouch cells: flexible sizing, higher space utilization, suitable for compact devices
Is a BMS necessary? How about long-term float charging?
A BMS is recommended for standalone use. For float charging, voltage should be controlled at 3.4V–3.45V with upper-limit protection to avoid overcharge damage.
What is required for parallel connection?
Cells must be strictly matched in capacity, internal resistance, and voltage to avoid circulating current and heat generation. We ensure consistency through full inspection and grading.
Can performance be improved in extreme cold environments?
Standard cells suffer capacity loss below -20°C. Low-temperature cells can retain over 85% capacity at -40°C.
Do you support long-term industrial supply?
Yes. We support OEM/ODM long-term projects with stable mass production and continuous supply capability.
