Basicly I want to get insane run time. I dont want to ever charge my RC CAR again.. just kidding.
I think instead of doing this to my E MAXX am going to convert my Losi LST2 Monster Truck.
Here are the packs im going to use, they are huge! I would like to stack about 6 of them on top of my lst2.
My plan for right now is to eliminate the whole transmition and run a direct drive low kv motor.
That way I would have a nice flat space on top of the lst2 to stack 6 cells for a nice 60,000 mah :P!!!

# Voltage: 7.4v
# Battery capacity:10000mah
# Discharge rate: 12C
# Size: 178mm (L) x 98mm (W) x 11mm ( thick)
# Weight: 530g
# Quantity:2
If I run this at 7.4v then I would have 60,000mAh @ 7.4v 720AMP<<<< Con LOL!!!!
At 60,000mAh the pack would be
7 Inch Long.
3.8 Inch Wide.
2.5 Inch High.
A very nice fit for top of the LST2, as long as I can mount the motor in the center and under. Im still trying to figure out if this will even work. I need to learn more about electricity...
All I have to do is find a nice low kv motor. Im just wondering if they make low kv motors that can run, on 7.4v. Also I am wondering how the Mamba Monster would react to a set up like this.
