You need to use a fast charging adapter and compatible cable. Prolly get both for total of $20 anywhere.I just put my batteries (Air 3) in the charger and let them do their thing. I didn't know that there was two speeds. How does that work?
if you want to know if you are fast charging or not - can save you hours and probably days/weeks in the long run if you can charge faster.Ok, I missed the point
This is false and outdated.If you can afford the time to slow charge you will get more cycles out of a battery. I have 18650's that I use for vaping that have lasted incredible time periods by charging at .5A. Having said that, obviously using DJI chargers you have no choice.
You should have added some commentary to explain the point you're trying to get across. The only thing your video shows are fast lights. It tells the viewer nothing about how to obtain a fast charge. That is why I said I missed your point. If you had said as much as your reply to @sarahb, that would have been suffice.if you want to know if you are fast charging or not - can save you hours and probably days/weeks in the long run if you can charge faster.
