Product Overview
The Longfeng 32140 is a single LiFePO4 battery cell, rather than a complete battery pack.
The 32140 designation refers to the cylindrical cell format, generally around 32 mm in diameter and 140 mm in length. Exact dimensions should be checked against the applicable datasheet when designing a battery holder, enclosure, or pack.
The cell can be connected in series to increase voltage and in parallel to increase capacity and current capability. A suitable LiFePO4 Battery Management System (BMS) should be included in the finished battery pack.
For example, four cells connected in series provide a 12.8V nominal battery pack.
Key Features
- 3.2V nominal voltage
- 15Ah (15,000mAh) rated capacity
- Approximately 48Wh energy per cell
- LFP (LiFePO4) chemistry
- 3C listed discharge rating
- Cylindrical 32140 format
- Rechargeable design
- Suitable for series and parallel battery configurations
Key Benefits
Straightforward Pack Sizing
The 3.2V nominal voltage makes it relatively simple to calculate common pack configurations. Four cells in series provide 12.8V, eight provide 25.6V, and sixteen provide 51.2V nominally.
With approximately 48Wh per cell, the nominal energy of a pack can be estimated based on the number of cells used and the final configuration.
Useful Current Capability
A 3C rating on a 15Ah cell corresponds to approximately 45A. However, the supplied information does not confirm whether the 3C figure represents continuous or pulse discharge.
The continuous and peak current ratings should therefore be confirmed before designing a battery pack around this value.
LiFePO4 Chemistry for Storage Applications
LiFePO4 is widely used in energy storage and electric mobility applications. It is generally regarded as more thermally stable than some other lithium-ion chemistries, while still requiring proper charging, protection, and pack design.
Flexible Battery Pack Construction
The cylindrical format allows cells to be configured according to the required voltage, capacity, and current. Proper cell matching and a suitable BMS remain essential for a reliable finished pack.

Always compare the application's required continuous and peak current with the cell's confirmed specifications. Additional cells in parallel may be required for higher-current applications.
Battery Pack Assembly Guidelines
When building a pack with Longfeng 32140 cells:
- Use a LiFePO4-specific BMS, not a BMS configured for NMC cells.
- Select the BMS according to the finished pack's voltage and current requirements.
- Use cells with matching specifications and, where possible, the same model and batch.
- Match cell voltage before connecting cells together.
- Use suitable cell interconnection equipment and materials.
- Keep excessive heat away from the cell body during assembly.
- Follow the applicable datasheet for charging voltage and current.
- Operate and store the cells within their specified temperature range.
- Do not use cells that are damaged, swollen, leaking, or otherwise compromised.

Frequently Asked Questions
What is the Longfeng 32140 15000mAh 3C LFP lithium cell?
It is a rechargeable LFP (LiFePO4) cylindrical cell with a 3.2V nominal voltage, 15Ah capacity, and a listed 3C discharge rating. It is supplied as a bare cell for custom battery pack construction.
What does 32140 mean in a battery cell?
32140 is a cylindrical cell size designation. It generally refers to a cell measuring approximately 32 mm in diameter and 140 mm in length.
Exact dimensions can vary, so check the applicable datasheet when the cell needs to fit a specific holder or enclosure.
What does 3C mean on a LiFePO4 cell?
The C-rating relates the allowable current to the cell's capacity.
For a 15Ah cell:
1C = 15A
Therefore:
3C = approximately 45A
However, the supplied information does not confirm whether the 3C rating is a continuous or pulse rating. Verify this before using it for pack design.
Is the Longfeng 32140 cell LiFePO4?
Yes. LFP and LiFePO4 refer to lithium iron phosphate chemistry, which is the chemistry listed for this cell.
What are the voltage and capacity of the Longfeng 32140 cell?
The cell has a 3.2V nominal voltage and 15Ah (15,000mAh) capacity.
Its nominal energy is approximately 48Wh, calculated as:
3.2V × 15Ah = 48Wh
How many 3.2V 15Ah cells are needed for a 12V battery?
Four cells connected in series provide a 12.8V nominal LiFePO4 battery pack, commonly referred to as a 12V-class battery.
Four cells provide approximately 192Wh of nominal energy.
For a 24V-class configuration, eight cells can be connected in series, while sixteen cells provide a 51.2V nominal configuration.
Parallel strings can be added when additional capacity or current capability is required.
How should I charge a Longfeng 32140 15Ah cell?
Use a charger specifically designed for LiFePO4 batteries rather than a charger intended for a different lithium-ion chemistry.
The exact charging voltage and current for this particular cell should be confirmed from the applicable datasheet before charging.
For multi-cell battery packs, use an appropriate LiFePO4 BMS for charge and protection management.
What is the maximum discharge current?
The supplied information lists a 3C discharge rating, equivalent to approximately 45A for a 15Ah cell.
However, the continuous and pulse ratings have not been independently confirmed. Verify these values from the applicable datasheet before designing a pack.
How many cycles does the Longfeng 32140 cell last?
The supplied information mentions 2,000 or more cycles, but the applicable test conditions were not provided.
Cycle life can vary significantly depending on charging current, discharge depth, temperature, operating current, and BMS configuration. The final figure should be confirmed from the applicable datasheet.
Is LiFePO4 safer than other lithium-ion cells?
LiFePO4 is generally regarded as having good thermal stability compared with some other lithium-ion chemistries.
That does not make a battery completely risk-free. Proper BMS protection, wiring, charging, cell matching, and assembly practices are still essential.
Can I use the Longfeng 32140 cell for solar storage and EV packs?
The supplied product information lists solar storage, inverter backup, EV, and e-rickshaw applications.
Suitability depends on the complete pack design, including voltage, capacity, continuous current, peak current, BMS configuration, and operating conditions.
Does the Longfeng 32140 cell have a protection circuit?
No. It is a bare battery cell and does not include a built-in protection circuit.
A completed battery pack should use a suitable BMS to provide protection against conditions such as overcharge, over-discharge, overcurrent, and short circuit.
What does A-grade mean for a LiFePO4 cell?
“A-grade” is commonly used as a seller or market term and does not, by itself, establish a universal technical standard.
For a proper evaluation, check the applicable datasheet and compare parameters such as capacity, internal resistance, discharge capability, manufacturing information, and test conditions.
Is 32140 the same as 33140?
No. 32140 and 33140 are different size designations.
A 33140 cell is wider than a 32140 cell, so the dimensions should be checked carefully before ordering cells for a specific holder or enclosure.
