Thanks guys. Ya I will be running a total of 16 cells. Sorry I didn't say so. Ha, an 8 cell setup would be pretty weak. I'm gonna try to get a nice set of matched 3300s that push some nice voltage.

I have a pair of B&T Matched Blister Packs rated at 1.200 Volts that pushed my HV-Maxx setup pretty well, but then I found out they were only rated at 20 amps so I'm lookin to get a nice pair of 8 cells somewhere near 1.200 Volts but at 30 amps instead of 20 for my new feigao setup. So you guys say the 9xl is the way to go for 16 cells then?

Thanks for the info guys!
