Default Any Performance Gain?

I have an E-Maxx on the way w/ the EVX esc & 2 3000 stick packs. I'm not new to r/c at all, but I'm just curious... If I switch the stick packs to side-by-side w/ battery bars would I get any performance gain? I think you would since there would be less resistance. I'm also going ot switch to Deans plugs. Any other electric opinions for th E-Maxx?

Hmmm, switching from the stock tamiya connectors to the deans will lower resistance going thru the plug. But as far as taking a stick pack apart and making it into the side-by-side pack with bars, i doubt that you would see a performance gain. If you buy new cells, say two matched packs and put them together, then you will see a gain.

I shortened the wires going to the motors, eliminated the bullet connectors completley, made a big difference. Also, build a couple of seven cell packs like on Traxxas' website. BIG difference!

Can the EVX handle 2 extra cells?

I am not sure how much of a gain you will notice, but since the welding used in stick packs probably isn't as efficient as how are parts are assembled side x side a gain probably will be there, noticeable? not sure.

Actually from what I have heard the stick packs can actually be better in terms of resistance compared to the soldered on bars for side by side packs. There is some talk that stick packs have less inductance too, but I don't have any real numbers to point you too. One thing to change though is the bar at the end of the pack that connects the two columns of cells together. If it is a little piece of tin like what is used to connect the other cells, replace that one bar so that isn't doesn't melt the shrink wrap and short the two end cells together. I had this happen on my 2000's in my e-maxx. I just replaced the one connection with a deans bar.

This may be a dumb question, but when I run the E-Maxx do I need to have the same mAh packs. Or can I run say a 3000 & a 2400? Or do they have be to the same capacity? Also, anymore E-Maxx electrical or mechanical tips would be great!

The EVX can handle two 7 cell packs with no problem. I race this way all the time. Yes, you need two similar packs. I good set of matched packs is the only way to be competitive. Try Promatch Racing, They offer 7 cell packs from 49 - 70 bucks. He can assemble them for you for a small price.

I have plenty of 3300 packs lying around... I'm sure I can find some guys around here to donate some 7 cell packs. I'm not gonna be racing, I just dont want junky stuff. All my cars are high performance with all the high-quality gear. I dont want the E-Maxx to be any different.
