FAQ

Is lifepo4 lithium ion?
Yes, Lithium Iron Phosphate (LiFePO4) is a type of lithium-ion (Li-ion) battery. LiFePO4 batteries are a specific type of Li-ion battery that use lithium iron phosphate as the cathode material. They have some advantages over other Li-ion batteries, such as a higher thermal stability and longer cycle life, but typically have lower energy density.
What is the nominal voltage lifepo4?
The nominal voltage of a lithium iron phosphate (LiFePO4) battery cell is typically around 3.2 volts. This means that when the cell is fully charged, its voltage will be around 3.2 volts, and when it is fully discharged, its voltage will be around 2.8 volts.

It's worth noting that the actual voltage of a LiFePO4 cell can vary depending on the specific application, the state of charge, and the temperature. In general, the voltage of a LiFePO4 cell will be highest when it is fully charged and lowest when it is fully discharged.

The nominal voltage of a LiFePO4 battery pack is determined by the number of cells connected in series. For example, a 12V LiFePO4 battery pack typically contains 4 cells in series, each with a nominal voltage of 3.2V. Similarly, a 24V pack contains 8 cells, a 48V pack contains 16 cells and so on.

It's also worth noting that while the nominal voltage of a LiFePO4 cell is 3.2V, the actual range of voltage of a single cell can vary between 2.5V to 3.6V depending on the state of charge and discharge.
What is the max voltage lifepo4?
The maximum voltage of a lithium iron phosphate (LiFePO4) battery cell can vary depending on the specific cell and the manufacturer, but it is typically around 3.6 volts. This means that the voltage of a fully charged LiFePO4 cell should not exceed 3.6 volts. Going above that voltage could damage the cell or reduce its overall lifespan.

It's also worth noting that, the maximum voltage of a LiFePO4 battery pack is determined by the number of cells connected in series. For example, a 12V LiFePO4 battery pack typically contains 4 cells in series, each with a maximum voltage of 3.6V. Similarly, a 24V pack contains 8 cells with a maximum voltage of 3.6V, a 48V pack contains 16 cells with a maximum voltage of 3.6V and so on.

It's important to keep in mind that the maximum voltage of a LiFePO4 cell should not be exceeded during the charging and discharging process. This can be achieved using a battery management system (BMS) or a specialized charger that is designed to charge LiFePO4 batteries to their maximum voltage.
What is the max charge voltage lifepo4?
The maximum charge voltage of a Lithium Iron Phosphate (LiFePO4) battery cell is typically around 3.65 volts per cell. This means that the voltage of a LiFePO4 cell should not exceed 3.65 volts during the charging process, going above that voltage could damage the cell or reduce its overall lifespan.

It's important to keep in mind that the maximum charge voltage of a LiFePO4 cell should not be exceeded during the charging process, this can be achieved using a battery management system (BMS) or a specialized charger that is designed to charge LiFePO4 batteries to their maximum charge voltage. This is done to ensure that the cells are not overcharged, which can shorten the battery's lifespan and cause safety hazards.

It's also worth noting that, the maximum charge voltage of a LiFePO4 battery pack is determined by the number of cells connected in series. For example, a 12V LiFePO4 battery pack typically contains 4 cells in series, each with a maximum charge voltage of 3.65V. Similarly, a 24V pack contains 8 cells with a maximum charge voltage of 3.65V, a 48V pack contains 16 cells with a maximum charge voltage of 3.65V and so on.
What is the lifepo4 dod?
The recommended DoD for a LiFePO4 battery is typically between 60-80%. This means that the battery should be recharged before it is discharged to a level lower than 60-80% of its total capacity. Going beyond this threshold could damage the battery or reduce its overall lifespan.

It's worth noting that high DoD will decrease the cycle life of the battery, and lower DoD will increase the cycle life of the battery. So, it's important to choose the right DoD for the application and use pattern.
What is the energy density lifepo4?
The energy density of LiFePO4 batteries is generally lower than other types of lithium-ion batteries such as lithium cobalt oxide (LiCoO2) or lithium manganese oxide (LiMn2O4) batteries. The typical energy density of a LiFePO4 battery ranges from around 110-160 Wh/kg and it could be higher or lower depending on the specific cell and the manufacturer.
What is the lifepo4 cycle life dod?
LiFePO4 batteries are known for their long cycle life, typically between 2000-5000 cycles depending on the manufacturer, DoD, and temperature. They have a relatively long service life, especially when compared to other types of lithium-ion batteries.
Can you offer the certifications for our lifepo4 battery packs?
We make some regular battery packs certificates every year. But most of our battery packs are customized for you. And we can help you to get the certification for your customized battery packs.
What is the warranty of your lifepo4 battery packs?

What is your MOQ of lifepo4 battery?
If it is our existing standard product, there is no moq requirement.
If it is a custom product, there is a MOQ requirement. However, the MOQ varies from material to material and you can contact us for specific information.
What is your terms of packing?
Generally, we pack the goods in neutral brown cartons. If you have legally registered patent, we can pack the goods in your branded boxes.
How can we pay?
You can pay via T/T, Paypal.
What is the resting voltage lifepo4?
The resting voltage of a lithium iron phosphate (LiFePO4) battery is the voltage of the battery when it is not in use or not being charged or discharged. The resting voltage of a LiFePO4 battery can vary depending on the state of charge (SOC) and the temperature.

When a LiFePO4 battery is fully charged, its resting voltage will be around 3.6 volts per cell. As the battery discharges, its resting voltage will decrease. When the battery reaches a state of charge (SOC) of around 50%, the resting voltage will be around 3.2 volts per cell, and when it reaches a state of charge of 0%, the resting voltage will be around 2.8 volts per cell.
Can I customize charge/discharge connectors for my lifepo4 battery?
It is possible. If you have a specific connector style request, please contact us.
