Just to correct your figures.
3.8v is the standard storage voltage of the pack and is not even down to the nominal voltage.
You are severely limiting your flight duration for no good reason.
3.5v is the standard cautionary voltage that may preserve your pack longevity.
At 3v a LiPo has no usable current left but can recharged OK, but you are degrading it.
2.5v is an unrecoverable voltage that most chargers will not attempt to charge, but they can be brought back, you should expect damage to that cell.
In between 3.5v and 3.2v is a very grey area where you may experienced very shortened life for some LiPo packs and not others.
LiPo’s aint LiPo’s (as an old Aussie add said about oils)
There are many different qualities out there, some good, some bad.
And no LiPo’s I work with can deliver the rated current.
Admittedly I work with larger packs mostly (3S to 12S, 3300mAh to 26000mAh typically)
