I have the extended batteries which take a full 1 hour and 40 minutes to charge with a 30W charger. I have a 45W charger also and I tried that on the 2nd extended battery and it still took 1 hour and 40 minutes to charge so the intelligent batteries must only accept up to a 30W charge at a time. I'm sure it has to do something with the batteries firmware keeping them from overcharging.
The faster you charge this battery chemistry, the faster the cells degrade. That is a fact.
Also, you can't stop your battery degrading, it started doing that the moment it was made.
You can slow the degrade to some extent by keeping the charge between 20% to 80% but you will need to go to 100% just prior to flight.
The longer the battery remains at 100%, the quicker it will degrade although not as fatal as going down to 0%
Flying in low temperatures only reduces the power output. Flying or recharging a hot battery (above the manufacturers max temp) will rapidly degrade the battery. Please note, it is the cell temperature that is important, not how hot the case is. The cells will be much hotter than the case when flying at full power on a hot day.
On the plus side, my mavic pro batteries are still pumping out close to their original flight time when i bought them back in 2017. I flight tested them 2 months ago. I charge and circle at about 20 metres until the 30% warning. |
