3.2V LiFePO4 Batteries & Cells
3.2V LiFePO4 cells are used in rechargeable battery assemblies and compatible solar lights. Cell format, capacity and protection requirements vary between small lighting batteries and larger pack-building cells.

View CategoryAbout 3.2V Cells & Batteries
3.2V is a nominal cell voltage commonly associated with lithium iron phosphate (LiFePO4 or LFP). A single cell is not a complete 12V or 48V battery pack. Series connections increase voltage; the finished assembly also requires suitable protection, connections and charging control.
For cells rated at 3.2V nominal, four in series give 12.8V and eight give 25.6V. These calculations describe an architecture, not a ready-to-use battery or permission to connect unmatched cells.
How to Compare 3.2V Cells & Batteries
| Selection criterion | What to compare |
|---|---|
| Chemistry | Confirm LiFePO4 rather than a visually similar 3.7V lithium-ion or primary lithium cell. |
| Cell format | Specify the full drawing and terminal details; a size code alone does not establish compatibility. |
| Capacity | Compare Ah under the stated discharge and temperature conditions. |
| Protection & assembly | Define whether a bare cell or protected assembly is needed, including BMS and mechanical support. |
3.2V Battery Project Requirements
Electrical
Provide the operating voltage window, required energy and continuous/peak current for your 3.2V project.
Mechanical
Provide cell-format constraints, terminal or tab details, assembly support and available dimensions.
Validation
Agree charging, load, temperature and equipment-integration checks for the selected design before ordering.
3.2V Battery FAQs
Is a 3.2V battery the same as a 3.7V battery?
No. The nominal voltage can reflect a different chemistry and charging profile. Do not substitute one for the other based on size alone.
Can a 3.2V battery be used in a solar light?
Only when the light and charge controller are designed for that chemistry and voltage. Match the original cell dimensions, terminals and charging specification.
Do you list every 18650 or 280Ah cell shown in searches?
No. Format and capacity are selection requirements, not proof that a particular model is listed. Send the exact cell specification for review.
