Want to reconfigure a 8mah 4s to a 6mah 4s

Sorry I didn't get to your PM earlier.

Anyway, unless 8Ah pack is configured as 4s4p 8Ah, and you removed two cells, you aren't gonna get 4s 6Ah. Chances are you have a 4s2p or 4s1p. If it's 4s2p, you can make a 4s1p, but it probably won't be good enough for much current-wise. If it's 4s1p, then removing a cell will make 3s 8Ah.
