Resource with professional pilots from DJI Studio talking about batteries usage in extreme cold conditions DJI Forum|Using batteries in the cold weather All we know that batteries used in DJIaircraft are Li-Po batteries. Li-Po stands for Lithium-Polymer, which means it allows us to withdraw a lot of power out of small battery pack. Basic knowledge: 1. Full charge your battery before each flight. 2. Never overdischarge your battery 3. Cycle the battery by discharging to 8% and full charging again every 20 flights 4. Intelligent flight batteries can automatically discharge themselves to enter storage mode 5. Discharge time depends on users settings and takes from 1 to 10 days Alright, let’s get back to our topic. Since Li-Po batteries are not made to fly below 0 degree C︒ battery performance can be not as good as in a normal temperature 5C︒ to 30C︒ Low temperature flight negative consequences: 1. Shorten flight time 2. Fast voltage drop Ways to prevent the issues described up there: 1. Never store packs in cold 2. Start the motors but don’t fly up, let your bird to warm up for a minute. 3. Please keep the aircraft hovering for 30 to 60 seconds before taking further action. 4. Do not keep the aircraft fully accelerated for long time. 5. Be gentle on a RC sticks 6. Outdoors keep your batteries in thermal insulation box with bag of hot rice (Uncooked rice warmed up in a microwave keeps temperature very good) 7. Inspire owners can use the battery insulation stickers 8. Inspire owners also can use a battery heater to pre-heat their batteries before the flight.
