Quark 125 - cutoff settings....

You need to program battery selection twice. Do manual the first time and select your voltage. This setting will now stay untill you change it again no matter what battery you choose.(I'm not sure what mode it runs in at this point, im thinking whatever setting was set last)

Then start programming all over and sellect your battery choice.

I switched back to 2.7, but I balance my packs often. (and i take a few risks :) )
