Firstly you do most of the charge at system voltage.You lost me on that one. How is it faster?
Secondly its faster because you don't have to break the pack.
Its been a while but here is what I did.
I charged the pack until the bms tripped at 3.55 volts.
I bled the high cell down to 3.4ish(with a capacity tester) which was in range with the others.
Then I charged until the bms tripped again.
Then I topped the cells indvidually to 3.625 volts with a charge voltage of 3.65 volts.
The longest cell took under <1 hour and the shortest cell took <15 minutes.
It probably took me longer to do all the joinery on the battery.
