Hello all. I have 3 mavic batts with 69-82-90 charges on them. I track them with AirData none have major deviations. I get on average 18 min mixed flying.. My Mavic is on 700. with some parameter tweaks I also use Dji go 4 4.06 and use the testcc. all three batts have lost some capacity over the last 7 months I live in S.W Florida so I fly a lot. when do you guys start to replace your DJI batts is a 150 charges expected?
