I see.
You're judging against your personal values.
There is no other 'system' to charge LiPos other than CC/CV. That is the profile.
To some modding a 2+ y/o a/c to avoid WAY overpriced batteries at the near-end of it's expected lifetime is satisfying.
Do you ever see a day when P2 batteries will not be available from DJI?
I cannot invest further in platforms that require proprietary batteries.
This is a way forward for some until the P2 is retired to the man-cave wall.
Then all of us will have to deal with it when that day comes.
