14.2 second 1/3 mile? (oval)

ok, what do you guys think batterywise....

will 96a constant / 128a burst be enough for a 7xl in this car?

and as for balancers.. I just read the thread about the eos 7i lba6 balancer here: http://www.rc-monster.com/forum/showthread.php?t=3971
it somewhat cleared up alot of questions i had about lipo.

questions:
can the Smart Balancer & Guard 505 balancers balance without being hooked up to the charger? do i just put a load on the charge input? or do i just plug it into the battery and it does it's thing?

would it be better to just get two lba10's, networked, and get a charger capable of charging 10s packs, and charge them wired in series?

would two lba10's networked work if I charged the packs seperatly, with my two 109's? if they're running off the same power supply?

help me make sure I'm doing the right thing. what would you guys decide if you were in my shoes?
