Depends how you look at it. I place all three of my batteries on the charging hub and leave it alone. The weakest charges first and so on. I don't have to keep looking to see if one is finished and go hook up the next. Very convenient.
Correct me if I'm wrong but I believe it starts charging the battery that is least depleted which ensures the shortest time before you have a charged battery for insertion into the unit. In addition, the controller is the last thing to be charged after all the batteries are done.
You may be right I may have that backwards but its the same result for me. I put them on when I get up in the morning if Im going flying, or the night before and they are always ready. My controller lasts the longest and I never charge it at the same time, It seems to charge up quite quickly. Now the mini 4 iPad is slow to charge and drains down standing still, that I have to keep up with the most.
Actually, I think that the DJI chargers tops off the battery with the highest residual charge first, so that you have a working battery as soon as possible, then proceeds to the next one, etc.
Same here, nice unit. After I fly I wait til the batteries cool, then put all 4 on "storage" mode which lets them sit at a healthy voltage until you are ready to charge them to fly again. OP: Do some reading here on the forum about battery use and storage. Never charge the batteries to 100% and let them sit around. Only charge them shortly before you're going to fly.
