Make sure you realize there are 3 components to an FPV Drone setup
Drone itself
Drone remote control
Drone First Person View goggles
Each one of those categories has possible accessories - The drone will need multiple batteries, the controller could have a crossfire modification (added range), the goggles could have different antennae or diopter corrective lenses. This page is going to basically talk about the Drone accessories like batteries, and multi-chargers for the batteries.. For example you would have close to 10 batteries you would want to charge 4 at a time. With small batteries you can expect the best performance of the drone due to less weight on the drone - longer lasting battery and faster speeds -- but only 3 minute flight times. I would buy several 1500mah batteries and a couple 6000mah batteries for 4S or 6S drones. The 'mah' is mill-amp-hours which is a measurement of stored energy. A 6000mah battery has 4x the storage of a 1500mah battery and could provide a longer flight time.
