The VEX AIR Drone comes with four total batteries: two each of the 900 mAh and 1200 mAh sizes. Each battery works slightly differently in terms of flight time and performance. This guide explains how to charge the batteries, read their indicator lights, and properly insert them before flight and remove them afterward.
Charging a Battery
To charge a battery, plug it into a power source using its USB-C port. Its indicator lights will begin blinking to show its current battery level as it charges, as shown in this animation.
When fully charged, all four indicator lights will stay solid green.
Indicator Lights
The battery has four indicator lights that help show the current status of the battery.
To see your battery's status, press the button on the battery to turn on its indicator lights. In this animation, after the button is pressed three indicator lights turn on which means that the battery is 50-75% charged.
Each light represents roughly 25% of the total charge, as shown below:
- 1 light — 0-25% charge
- 2 lights — 25-50% charge
- 3 lights — 50-75% charge
- 4 lights — 75-100% charge
Battery Sizes
The VEX AIR Drone uses two different battery sizes, each with its own advantages and trade-offs:
- 900 mAh — Lighter in weight, allowing the drone to fly faster, but provides a shorter flight duration.
- 1200 mAh — Offers longer flight time due to higher capacity but adds extra weight, which can reduce the drone's top speed.
Inserting a Battery
To install the battery, hold it so the Up arrow is facing upward and pointed toward the drone, then slide it straight into the compartment until it clicks into place.
Note: Inserting the battery will automatically turn on the drone.
Removing a Battery
To remove the battery, first power off the drone completely, then grip the battery's pull tab and gently pull it straight out of the compartment.
