FPV Battery

 

Definition: An FPV battery is a rechargeable power source specifically designed for powering FPV (First Person View) equipment, such as video transmitters, cameras, FPV goggles, and other accessories. It provides the necessary electrical energy to operate these components during drone flights or FPV sessions.

Functions: The main function of an FPV battery is to supply consistent and reliable power to the FPV equipment. It ensures uninterrupted operation of the FPV system, allowing for continuous video transmission, camera recording, and powering other essential components.

Types: There are different types of FPV batteries available, and the selection depends on the specific needs and requirements of your FPV system:

  1. Lithium Polymer (LiPo) Batteries: LiPo batteries are the most commonly used type in FPV applications. They offer high energy density, lightweight design, and can deliver high current output. LiPo batteries come in various cell configurations such as 2S, 3S, 4S, and higher, indicating the number of cells and the voltage.

  2. Lithium-ion (Li-ion) Batteries: Li-ion batteries are similar to LiPo batteries but have a different chemistry. They offer a longer lifespan and better stability compared to LiPo batteries but have a slightly lower energy density. Li-ion batteries are commonly used in high-end FPV applications.

  3. Nickel Metal Hydride (NiMH) Batteries: NiMH batteries are older technology but are still used in some FPV setups. They offer lower energy density and higher weight compared to LiPo batteries but are known for their reliability and affordability.

Parameters: When selecting an FPV battery, consider the following parameters:

  1. Capacity (mAh): The capacity of the battery determines how long it can power the FPV equipment. Higher capacity batteries offer longer flight or usage times but are generally heavier.

  2. Voltage (V) and Cell Count: The voltage and cell count of the battery should match the voltage requirements of your FPV system. Common FPV batteries have cell counts ranging from 2S (7.4V) to 6S (22.2V).

  3. Discharge Rate (C): The discharge rate indicates how quickly the battery can deliver power. Higher discharge rates are essential for FPV applications that require high current output, such as racing drones or powerful video transmitters.

Selection Method: Consider the following factors when selecting an FPV battery:

  1. Compatibility: Ensure that the battery is compatible with your FPV system's voltage requirements and connector types. Check the manufacturer's specifications for compatibility information.

  2. Capacity and Flight Time: Determine your desired flight or usage time and select a battery with an appropriate capacity to meet your needs. Consider the weight and size of the battery as well, as it can affect the drone's performance.

  3. Discharge Rate: Select a battery with a suitable discharge rate based on the power requirements of your FPV equipment. Higher discharge rates are preferable for more demanding applications.

Precautions: When using FPV batteries, follow these precautions:

  1. Charging: Use a compatible charger designed for the specific battery type and follow the manufacturer's instructions for proper charging procedures. Avoid overcharging or charging at high currents, as it can damage the battery.

  2. Storage and Transportation: Store and transport batteries in a cool, dry, and fireproof location. Avoid exposing batteries to extreme temperatures, direct sunlight, or water.

  3. Handling and Maintenance: Handle batteries with care, avoiding any physical damage or puncturing. Inspect batteries regularly for any signs of swelling, damage, or wear. Dispose of damaged or swollen batteries properly.

Brands: There are several reputable brands that offer FPV batteries. Some popular brands include:

  1. Tattu

These brands are known for producing high-quality FPV batteries with good performance and reliability. When selecting a brand, consider factors such as battery capacity, voltage, discharge rate, and compatibility with your FPV system. Additionally, read reviews and feedback from other users to gauge the performance and durability of the batteries.

It's important to choose a reputable brand to ensure the safety and performance of your FPV system. Poor quality batteries may have insufficient protection circuits, leading to safety hazards such as overcharging, over-discharging, or overheating. Always follow the manufacturer's instructions and guidelines for safe usage, charging, and storage of FPV batteries.
