How to Properly Charge and Discharge Your FPV Battery for Maximum Performance and Longevity?

FPV Battery

Flying a first-person view (FPV) drone can be an exhilarating experience. However, it requires careful attention to the drone’s battery to ensure optimal performance and longevity. Properly charging and discharging the FPV battery, and choosing the right battery for your drone, are crucial steps in maintaining your FPV drone’s battery. 

Failure to follow these steps can lead to reduced performance, shortened lifespan, and even dangerous situations such as battery fires. In this article, we will discuss how to properly charge and discharge your FPV battery for maximum performance and longevity, and tips for choosing the suitable battery.

Choose the Right Battery

Choosing the appropriate FPV drone battery is crucial for its performance and longevity. When selecting a battery, it is essential to consider its capacity, voltage, and discharge rate. For instance, a higher-capacity battery will provide longer flight times. On the other hand, a battery with a lower discharge rate may not be able to deliver the necessary current for high-performance flying. 

It is also important to choose a battery that suits your drone best with the correct voltage for your drone’s power system. Using a battery with too high or too low voltage can cause damage to your drone’s components. Always use a battery recommended by the manufacturer or consult with experts in the FPV community for guidance.

Charging Your FPV Battery

Charging your FPV battery is an essential step in ensuring your drone performs at its best. Here are some tips to help you charge your FPV battery correctly:

a. Use the Right Charger

Using the correct charger is essential when charging your FPV battery. It is important to use the charger that comes with your battery or a charger recommended by the manufacturer. Using the wrong charger can damage the battery or even cause a fire. Different batteries have different charging requirements. Using the wrong charger can overcharge or undercharge the battery, leading to reduced performance and a shorter lifespan. Always read the manufacturer’s instructions carefully and follow them closely when charging your FPV battery.

b. Charge at the Right Voltage

When charging the FPV battery, it is important to charge it at the correct voltage to ensure optimal performance and avoid damaging the battery. Overcharging or undercharging the battery can lead to decreased flight time and potentially damage the battery. Most FPV drone batteries have a recommended voltage range for charging, which you need to follow for lasting performance. It is also crucial to use a charger specific to your drone battery to ensure charging it to the correct voltage.

c. Charge at the Right Amperage

Charging your FPV battery at a suitable amperage is crucial for proper charging and longevity. The indication of the amperage at which you should charge your battery is available on it. Charging your battery at too high an amperage can damage it and reduce its lifespan while charging it at too low an amperage can take a long time. Always use a charger that can provide the appropriate amperage and follow the manufacturer’s instructions to avoid damaging your FPV battery.

d. Charge in a Safe Location

Charging your FPV battery in a safe location is crucial for your safety and the safety of your surroundings. Always charge your battery on a fire-resistant surface, such as a concrete floor or a ceramic tile, away from flammable materials. You must use a lipo-safe bag or a charging container to contain any potential fire or explosion. Never leave your battery unattended while charging, and after charging it fully, it’s crucial to disconnect it from the charger.

Discharging Your FPV Battery

Discharging your FPV battery is also crucial for its performance and longevity. Here are some tips for discharging your battery:

a. Avoid Over-Discharging

Over-discharging your FPV battery can have serious consequences causing it to swell or leak. To avoid over-discharging your battery, constantly monitor its voltage during use and land your drone before the battery voltage drops too low. It is also recommended to use a low-voltage alarm to monitor the battery voltage during flight. Never leave a discharged battery unattended, and always store it at a storage charge if you will not use it for a while.

b. Storage Charge

A storage charge is a recommended charge level for long-term storage of FPV batteries. It is typically around 3.8 to 3.85 volts per cell for lithium polymer (LiPo) batteries. Storing a battery at a full or low charge level for an extended period can reduce its lifespan and even cause it to swell or leak. To store your FPV lipo batteries at a storage charge, use a compatible charger or a storage charge device. Always follow the manufacturer’s instructions, and never store a damaged or puffy battery.

c. Discharge Carefully 

Discharging your FPV battery is crucial for its performance and longevity. Avoid discharging the battery too quickly or deeply, as this can damage the battery or reduce its lifespan. Using a low-voltage alarm or a telemetry system is recommended to monitor the battery voltage during flight and land the drone before the battery voltage drops too low. If you need to discharge the battery for storage or transportation, use a compatible discharger and follow the manufacturer’s instructions carefully.


Properly charging and discharging your FPV battery is essential for maximising its performance and longevity. Using the appropriate charger and charging at the correct amperage can prevent damage to the battery and ensure optimal charging. Consult experts at RC Battery to learn more about the right charging instructions for FPV batteries. 

Storing your battery at a storage charge level and discharging it can prevent reduced lifespan and swelling or leaking. Always follow the manufacturer’s instructions and use recommended charging and discharging practices to keep your FPV battery performing at its best.
