Amazing technology these P3 batteries.

Gave my drone full up and forward acceleration this test this afternoon after doing a deep discharge and recharge on the battery. ( I had 1 cell that was dropping a little) Now all cells are within a few mV of each other.

Getting 27.3 amps being pulled from the battery during this period of high acceleration.
Temp at time 29c

Only rose slightly

I agree these are good batteries.

I do deep discharge and charge when I see its capacity has degraded by ~10%. It recovers back to almost original capacity. This is better way of deciding when to go for deep discharge charge cycle. I don't follow a thumb rule of 20 charges before deep discharge.

i had a flight which flagged up battery weak on take off. (in logs drawing 20amps)
I guess battery has had 30 cycles or cycles or so.

now seems good as new.
