Charging LiPo batteries is one of those things every FPV pilot does all the time, but it is also one of the areas where bad habits can cause the most problems. A good charging routine keeps your batteries healthier, your flights more consistent and your workspace safer. A bad routine can shorten battery life, create unbalanced cells, damage packs or, in the worst cases, start a fire. In the previous article, we talked about what LiPo batteries are, how they work, how they differ from Li-ion packs and how to store and discharge them properly. This time, we will focus on charging: modern chargers, balance charging, storage mode, discharge mode, internal resistance, charging at 1C, charging times, parallel charging and the most common mistakes to avoid. Modern LiPo Chargers Modern LiPo chargers are much better than the basic chargers many people started with years ago. A good charger today does much more than simply push current into a battery. A proper FPV charger can read the number of cells, monitor each cell individually, balance the pack, charge at a chosen current, discharge the battery, bring it to storage voltage and often measure internal resistance. This is why using a real…

If you build or repair FPV drones long enough, you will eventually run into a noisy quad, hot electronics, random video interference, or a build that feels harder to tune than it should. In many of those cases, one small and cheap part helps more than people expect: the capacitor. Here is the short answer first: Yes, most 4S and 6S FPV drones benefit from a capacitor. A capacitor helps reduce voltage spikes and electrical noise from the ESC and motors. On analog builds, it often improves video noise. On digital builds, it can still help with power stability, dropped frames, and overall reliability. For many 5-inch FPV drones, a low-ESR capacitor in the 470uF to 1000uF range is a common choice. The best place to install it is usually directly across the main battery pads on the ESC or AIO board. If you want the practical answer from a real FPV pilot: I would add a capacitor to almost every 5-inch or larger quad, and I would strongly consider one on any build that runs 4S, 6S, larger motors, or a power-hungry digital system. Introduction What Is an FPV Capacitor? One of the most prevalent parts of an electronic system is…

The most underrated FPV component, in my opinion, is the drone antenna. However, wireless communication between the radio and radio receiver, or the video transmitter and video receiver, would not even be imaginable without antennas. I'll show you how to select the ideal one for your FPV drones in this article. What is an FPV Antenna? An FPV antenna is necessary for all radio equipment to operate. Your smartphone, in case you were unaware, also contains many antennae. A component used to transform electrical video signals into radio signals and broadcast the signal is an FPV antenna. Additionally, it takes in airborne radio signals and changes them back into electrical visual signals. Both the FPV video transmitter and video receiver have FPV antenna mounted. Both VTX and VRX cannot function effectively without antennas. The active element, coaxial cable, and connector are the three components that make up an FPV antenna. The active element is the essential element for radio transmission and reception; a connector is necessary to connect your VTX or VRX; whereas the coaxial cable only connects the two. How Does an Antenna Work? A transmitter antenna and a receiver antenna are required for anything wireless. Wi-Fi, Bluetooth, and other wireless…

Brushless motors are the heartbeat of modern drones, RC vehicles, e-bikes, and countless precision devices. If you're wondering how long brushless motors last, you're not alone.
