How to fix a drone that fell in the water?
Things to know
Drones are not built to survive water, and they are definitely not capable of swimming or landing on water. Prolonged water exposure will most likely ruin the battery and full submersion is almost certainly a dead-end. Acting fast is the key. The least time in the water, the higher the chances it will survive.
Whether you got really unlucky or you just want to learn what to do in case it happens, we’ve got you covered with this simple guide.
1. Take it out of the water immediately
Act fast and take it out as soon as possible. If it fell in saltwater you can optionally rinse it with deionized (distilled) water. Salt is more corrosive and tends to wreck internal components even after it dries out.
2. Take the battery out
Right after you take it out of the water, you need to take the battery out. Be careful to not burn yourself. Lithium-ion batteries in short circuit tend to overheat very quickly and could burst into flames.
3. Dry for as long as possible
Leave it in a dry, cool place, until all the water evaporates. This can take up to 5 days. Alternatively, you can place it in a bowl of rice that will absorb water.
4. Turn on and assess the situation
Clean the legs, rotors and area around the camera. We recommend using a different battery for the initial power-up.

Tips for extending the life of your batteries
1. When not used for a long period of time, store at 40-50% charge and in stable temperature between 70-82°F/ 21-28°C.
2. The batteries should go through a discharge/charge cycle at least once every 3 months.
3. Avoid flying in temperatures below 32°F / 0°C and above 104°F / 40°C.
4. Avoid completely draining batteries every time you fly.
5. Let the battery cool off before recharging after the flight.
Tips for fast return to home
1. Switch to sport mode.
2. Lower the altitude.
3. Use the full throttle to fly back home.
