Well I made an 8s A123 pack and it doesn't work with the Quark... I plug it in and turn the switch, it makes an alarm beeping sound (obviously for over-voltage protection)
Well, I think I am going to get either some flightpower EON X30's, or the ThunderPower 40C packs... I am thinking more towards the TP packs however just because of the best voltage holding ability. I am sure they are both good choices.
I just need the E-revo chassis now...
