More Battery Safety Tips
It seems like quite an obvious tip but don't use a battery with any known or visible damage including

leaking and swelling. It could result in a drone crash or even worse and is simply not worth the risk. A new
battery is a fraction of the cost of the drone, so just don't risk it.
If your battery comes into contact with water, stop using it immediately and don't use it again. Allow the

battery to dry in an open area.
You should also keep in mind weather conditions such as fog and mist can result in water on your aircraft

and batteries, so you will need to take care.
If a battery ever catches fire, do not use water to put it out as this made spread the fire. Use sand or fire

extinguisher designed for electrical fires.
Store batteries at room temperature in a dry and ventilated place. Never leave batteries in the aircraft as a

battery error could result in lasting damage to your drone.
For added safety, batteries can be stored in a fireproof bag or metal case to avoid issues.

Short-term Storage – Batteries should be discharged to between 60 and 80% if you're not using them for

between one and ten days.
Long-term Storage – If storing for more than ten days, store the battery between 40 and 60%. Batteries

should not be left for over three months without being charged as the battery life will be reduced.
Intelligent Flight Batteries will automatically discharge after a specified amount of time. You maybe able to

set this feature in your drone app if your drone supports intelligent flight battery.
Never store batteries in vehicles other than during transportation. The conditions are usually too hot/cold

and can cause damage to the battery.
Plan your drone's flights so that they are comfortably within the limits of the battery.

Pro tip: leave a little extra time at the end of each flight in case your drone needs a little extra power for

any reason, for example, to counteract strong winds or to hold its position while waiting for the landing
zone to clear.
The lower you push a battery's charge—hitting regularly below 20%—the shorter that battery's life, and

the lower its reliability, will be.
In low temperatures, or when there are strong winds, adapt your missions with shorter flight times in

mind—when winds are strong, your drone uses more power, while low temperatures cause the chemistry
of the battery to change and it to discharge more quickly.
In cold conditions, where the air temperature is below 5° C (41° F), try to keep your UAV's batteries

warm—ideally at least 5° C—before connecting them to your drone.
Final Pro Tips that may save your drone, you, your house and your life
Handle Drone batteries with care and extreme caution

Never charge drone batteries unattended.

Invest in fire proof safety equipment and fire extinguishing supplies.

Don't try to save money thinking your can still use a damaged and or swollen battery. Buy a new one and

be thankful. Dispose off damaged batteries properly.
Fly with responsibility and have fun.
