These batteries are lithium polymer and do not hold a memory.
The old story of discharging to 50% and recharge a few times on new batteries came about on old nicad batteries to get them to maintain maximum performance.
Lithium polymer don't need that attention and are sweet to use to full potential right from factory.
The only 3 factors to maintain with LiPo is don't discharge below 10% (DJI auto set in Go4 to 30%) 2, dont leave fully fully charged for to long ie more than a week. (again DJI smart circuit auto discharges to storage charge if left alone) 3, dont charge while hot (again you can't do this with DJI batteries as smart circuit won't allow charging if temp is over limit)
So main thing is dont discharge too low, keep them cool and use them regularly.
