Coolhand,
The Power Supply is going to be a modded computer power supply. I'm getting a guy thats known for good work to make a bunch for us at a reasonable price. I've been pushing mine to the limits this weekend (3 chargers at once - 5A each!) and its been working great. It has outputs for 12v, 5v, and 3.3v. We're also coming out with a power supply distribution block - you can hook up a bunch of chargers to one 12v line (on the PSU) and it keeps the wires from getting tangled etc - a very very nice unit in my opinion - I absolutely love mine. Maybe when you pick up some Li-Mns we can work out a package deal.... Btw, do you have an E-revo? I'm thinking of building one up and can't decide if it will perform better than my E-maxx.....

Hippie,
I'm the owner of Boom Boom Batteries - we're somewhat established (our stuff is sold on RC-monster), but I can see you wanting to buy from the big guys. No offence taken.
