Never use after market Chargers:
If you use after market chargers there maybe a chance those chargers will not stop charging when battery

is fully charged and or over charge the battery and its cells, may not cut off the power in time when battery
cells are full. It will damage the built in Battery management unit. Over Charging can lead to battery cells
heating up, swelling and immediate explosion causing fire around it.
We highly recommend to always use only stock supplied chargers that come with drones. Never leave the

batteries unattended when charging. Please read more caution and advise, tips regarding charging below
in this document.
Using Drone Batteries
Let's begin with some general tips on using the batteries in your aircraft.
1. Start off by downloading and reading the manual for your specific flight battery and drone before taking
them out for a flight. Make sure you understand the basic functionality before you fly. Pay particular
attention to the section on the Intelligent Flight Batteries.
2. Only fly your drone with a fully charged battery that is securely mounted in the aircraft. As part of your
pre-flight checklist, you should ensure the batteries are properly fitted and charged to 100%.
3. Never install or remove a battery from an aircraft when it's turned on.
4. Avoid flying your aircraft erratically. This includes sudden changes of direction or abrupt braking. This will
quickly drain the battery as the motors will be working harder than they need to. Try to keep your operation
to steady movements and slow braking for longer flight times. We understand that this isn't always
possible but for general drone use, you should aim to follow this tip.
5. Make sure you follow the operating temperature guidelines found in the user manual for your aircraft.
Flying in cold temperatures will reduce your battery capacity and warm temperatures may lead to
irreversible battery failure.
6. If you have multiple batteries for an aircraft, it's recommended you cycle through your batteries and avoid
using just one. Balance the pressure you put across your batteries. Label your batteries may help.
7. At least every 20 cycles, complete charge and discharge the aircraft's battery. This will help optimize the
life cycle of the battery. Unlike previous LiPo batteries, this won't cause lasting damage to your battery as
long as you limit how often it's done.
8. Keep the connectors on your batteries, chargers and aircraft clear of debris and dust. The connectors can
be cleaned with a clean and dry cloth or compressed air canister. Be careful when cleaning to avoid
damage to the connectors. Never use sharp pointy and metal objects or tools to clear the debris or
connectors of your battery or drone. The metal object can cause short circuit and damage to battery and
or immediate fire.
9. If you encounter a battery error, try running your battery down to 0% then recharging. Unlike previous LiPo
batteries, Intelligent Flight Batteries retain some charge which helps avoid irreversible errors when
discharging a battery.
