At least not as a scheduled maintenance, as mentioned for older aircrafts. You should only consider a deep cycle if you encounter some voltage reading issues or something to that effect.
Hi Jamie - Way back, there were posts on the Phantom forum about deep cycling now and then. There was mentioning of it recalibrating the percentage scale (i.e. resetting what is 0 and what is 100%). I tried it on one of my used P3A batteries at the time, and it seemed to gain some usage. I did, however, notice that it ran until WELL past 8%. In fact, it ran down to 0 percent and kept going. I let it go until shutdown. After completely cooling down, I gave it a full charge. Cells looked much nicer balanced when I was done. It worked so well, I decided to do my second battery. That one ran until about 7-8% and was done. It shut down at that point. Similarly, I let it cool and recharged completely. I'm still using them today. I don't get a lot of flights due to my weather and lack of interesting places to fly, but wanted to bring up the low-end calibration idea to introduce into this conversation. Do you have any DJI studies backing up any of this, or for that matter, debunking it?
I'm loving my new Mavic. I've got two batteries for it and I'm holding one of them back, not using it, to kind of preserve it. I've done now deep discharge on it and won't until I think there is something not quite right. It appears in the above paragraph that the main thing it did was to 'reset' the calibration points and more equally balance the cells. So far, no issues with the Mac.
Thanks for any info you might be able to bring to the table on battery usage. I don't care about "DJI's official recommendation", but care a lot about getting the maximum life out of my batteries.
