Battery Maintenance
5. Never drop the battery into water, or store it in places where there is a possibility of water leakage.
6. Do not drop, strike, impale, pierce, or manually short-circuit the battery.
7. Keep the battery away from metal objects, such as watches, jewellery, and hairpins.
8. Never transport a damaged battery, or a battery with power level higher than 50%.
9. Discharge the drone battery to ~50% before transportation. (The suggested storage voltage level of
the drone is 11.1~11.6V, and the radio controller is 50%)
1. Never use the battery when the temperature is too high or too low.
2. The ideal storage temperature is 22°C ~ 28°C.
3. Discharge the power to ~50% (11.6V) when you are not going to use the drone in the coming days.
4. During long term storage, the batteries needs to be checked and charged back to ~50% (11.6v) every 3
months
5. Never over discharge the battery, otherwise the battery cells will be damaged.
6. Do not charge battery immediately after flight, because the battery temperature may be too high.
1. When flying over water, avoid allowing the drone to drop or crash into the water from a high altitude as
this could cause major damage to the drone.
2. Don't expose the drone & battery to direct sunlight for sustained periods of time as this can raise the
internal temperature of the drone to well above the operating temperature range
3. Please check propellers before each flight. Distorted or damaged propellers should be replaced
immediately.
4. After flying over the sea, sand or water, the Spry+ drone and remote controller must be thoroughly
washed with fresh water within 2 hours and dried - especially the motors.
5. It's strongly advised to rinse the drone before the salt crystalizes. * Salt remaining on the waterproof
membrane affects drone performance and may cause a crash.
6.
Motors are best rinsed by removing the propellers and immersing the motors one at a time into a bucket
of warm water and arming the drone so the motors spin.
7. In the event of the Spry+ not being used for a long time, please store the drone and the batteries in a dry,
and ventilated environment at 20°C~25°C.
8. Please refer to <Batteries> for further details on maintaining the batteries.
9. The function of waterproof membrane is to ensure that the aircraft barometer can detect the current air
pressure and prevent water from entering the aircraft. There are two possibilities of damage to the
membrane:
a. Blockage, such as frequent flying in sea water or sewage environment, not fully washed after flying,
resulting in salt or sludge sticking to the membrane. At this time, the height-lock function of the aircraft will
be lost, and the aircraft may rise or fall all the time.
