6 things you should know when using LiFePO4 battery

6 Dinge, die Sie bei der Verwendung von LiFePO4 Akku wissen sollten

As you may have noticed, LiFePO4 batteries are becoming increasingly popular, replacing the batteries used in things like solar panels, RVs, golf carts, bass boats and electric motorcycles as they are by far the best.

In this article we provide brief instructions on how to handle LiFePO4 batteries and give you tips on charging, protection and the optimal temperature. LiFePO4 lithium batteries offer some great advantages over traditional lead-acid batteries, including the fact that they are super light, safe, have higher energy density, have a much longer lifespan and require less maintenance.

Although LiFePO4 lithium batteries require little maintenance, there is still something we need to pay attention to.

1. Charge

Take the Timeusb 12V 100Ah Pro LiFePO4 Lithium battery as an example. The recommended charger should support charging lithium iron phosphate (LiFePO4) batteries. And to fully charge the battery, the DC charging voltage should be between 14.2V and 14.6V and the charging current should be less than 100A.

The voltage levels that the LiFePO4 battery reaches in different charging phases. (Take Timeusb 12V 100Ah Pro LiFePO4 battery as an example)

Voltage type


Nominal voltage of the cell


Peak voltage of the cell


Overcharge voltage


Discharge voltage


Charging a LiFePO4 battery involves two steps to increase the state of charge (SOC) to 100%. The first step is constant current charging. In this step, the charger supplies the LiFePO4 battery with a constant current. The voltage level floats until it reaches 14.6V. Until this point, the charger charges the battery with a constant current. However, when the voltage reaches 14.6V, the charger stores the voltage and keeps it constant. At this point, the battery charge level is about 90%. From here the charger outputs a decreasing current to the battery while the voltage remains constant at 14.6V. When the SOC reaches 100%, the charger will automatically shut down and stop charging the battery.


1. Keep away from water while charging.

2. The best charging temperature is 0-45°C, which can accelerate the movement speed of the internal chemical material. Then we can load faster.

3. When charging is complete, please do not plug your charger and LiFePO4 battery together.

2. Comprehensive battery protection

Lithium batteries occasionally experience deep discharge. The lowest value of voltage with which you can discharge a LiFePO4 battery is 8.8V. Timeusb LiFePO4 battery has an integrated BMS to protect against overcharging, over-discharging, over-current and short circuit as well as an excellent self-discharge rate. Without BMS protection, the battery can be destroyed by discharging even at a voltage below this voltage, and the destruction would be irreversible. This means that if you discharge the battery to less than 8.8V, the damage would be permanent.

Therefore, it is important to stop using the battery before this period expires. The LiFePO4 batteries from Timeusb are equipped with such a BMS board for self-protection.

3. Temperature influence

Temperature is one of the critical factors that can affect the performance of the battery. The lower the temperature, the lower the available capacity. At a temperature below 0 degrees, most LiFePO4 lithium batteries cannot be charged at all.

The battery can operate at a temperature of -20℃ to 60℃, a temperature between 10℃ to 35℃ is ideal for long-term storage. Store in a fireproof container and out of the reach of children.

4. Avoid deep discharge

While LiFePO4 batteries can be safely discharged up to 100%, it is generally recommended to avoid deep discharge if possible. This is because LiFePO4 batteries only have a limited number of charge and discharge cycles and deep discharge can shorten their overall lifespan. Ideally, LiFePO4 batteries should be charged once they have reached 20-30% capacity.

5. Storage

If you are not going to use your LiFePO4 battery for a long period of time, it is important to store it properly to avoid damage. Store the battery fully charged in a cool, dry place out of direct sunlight. You should also charge the battery every few months when not in use.

6. Quality is important

Finally, it is important to choose high-quality LiFePO4 batteries from well-known manufacturers. Although there are many cheaper LiFePO4 batteries on the market, they often have lower energy density and shorter lifespans than their more expensive counterparts. Investing in a quality LiFePO4 battery can save you money in the long run by offering better performance and a longer lifespan.
