FPV racing cars and freestyle drones are energy hungry machines! At least four high-speed motors drive propellers at tens of thousands of revolutions per minute. The power systems on these drones range from 4.2 volts (V) for micro UAVs to 25 volts for high-power micro four axis vehicles. Voltage is very important, but amperes can generate energy! The engines of racing cars and freestyle UAVs pull on 25 amperes, multiply by four motors, and we have a 210mm UAV that can use 100 amperes to punch holes at high speed! This speed has special requirements for batteries. At present, the choice of battery is a lithium polymer battery, called “lipo”. “These batteries can provide a strong current that matches the requirements of the motor. They are small enough to be installed on a UAV, and the energy density is high enough for us to fly for a few minutes. These batteries can also be recharged, so the FPV drone battery charger is a key component of your FPV armory!
The FPV battery charger we use is an intelligent technology. Using microprocessor controlled circuits, this FPV drone battery charger monitors the condition of the battery and changes the voltage and current throughout the charging process to optimize charging and prevent damage to the LiPo battery. Most modern UAV battery chargers can be charged at various voltages. For example, glasses batteries may need 8.4v, while UAV batteries may need 16.8v or more. The UAV battery charger should be able to easily charge at a variety of user selectable voltages. In this way, the UAV pilot can charge all his batteries with one charger, including radio transmitter batteries, FPV video receiver batteries, goggle batteries, and many different types of UAV batteries.
Balance charge and battery type
For the safety of UAV batteries, it is crucial that batteries occasionally “balance” their individual batteries, which means that the charger will adjust or increase or decrease the voltage of each battery in the battery to make them match. Modern battery chargers will have “balanced” ports so that a single battery in a battery pack can be balanced. Despite different uses for UAV enthusiasts, most battery chargers on the market are able to charge a variety of types of batteries, except for the lipo. For example, most chargers can also charge like the lead-acid or nickel cadmium batteries in your car. The control circuit can adjust the voltage and charge rate, as well as the total charge applied to the battery. This makes the battery charger a very useful tool on the home work platform
On site charging
No one likes to wait for the battery to charge when a friend flies without a battery. This can be avoided by having a large number of batteries or a battery charger, which can do two things: 1) charge on site and 2) charge multiple batteries at the same time. Today’s battery chargers can often use many input power sources, from alternating current (AC) in your home to direct current (DC) from car batteries or other larger batteries. In addition, it is important to pay attention to whether your battery charger has a built-in AC / DC converter, so that it can be directly plugged into the wall socket in your home. Without it, some battery chargers require an external AC / DC converter. Many battery chargers have multiple outputs. If necessary, they can charge multiple batteries separately at different voltages and charging rates at the same time. The ability to use battery chargers, utilizing DC inputs, also has multiple outputs, allowing pilots to charge multiple batteries on site. It’s a huge advantage when the game is blocked out of the best path, or there’s no exit available. It’s also very cost-effective, because you don’t need to buy so many batteries to enjoy a whole day’s flight!
FPV drone battery charger is a key component of UAV enthusiasts’ collection. They are versatile and can charge batteries of any type, size and voltage. They are also a key component of UAV power system security. Although lipid batteries are safe, they can cause fire, especially when used improperly. Modern battery chargers use intelligent programming to help your battery use for a long time without damage or danger. Battery chargers are becoming miniaturized, and some units can be installed in your palm! There are many good chargers on the market, and many of them have very similar menu functions, allowing you to choose battery type, battery voltage, charging rate, and some can even monitor battery temperature and other conditions. Be sure to charge your lipid battery in a fireproof lipid bag and never leave the rechargeable battery unattended.
