what do you mean by this.....I have (2) 6 cell packs wired in series.....which equals 12 cells...in side/side configuration...in the past I've run (14) & (16) cells....saw some benifit.... but not much.....as is it's hard to keep the front end on the ground...in either gear.......when i went up in cells it was damn near unreal and uncontrollable at times.....I don't race but I have it set up to race...there is a few races going on near me.....the one RC monster is sponsering is only like 3 hours away......I want to go....but it depends on hte finances at the time....I guess time will tell.

In series, i'm thinking more wires aren't there? What are the benefits to run in series vs parrallel? My batts are designed for the emaxx, so i could put the heavy end up front which will help. Also, if you have a flm chasis or gorilla, the batteries can be flat and even weight?

That's right, your in NY! I'm way over here in MN!

Having 12 cells wired in series is the same thing as having one battery pack that has 12 cells in it. You can have two 6 cell packs and to wire them in series you take the negative of one pack into the other packs positive, then you wire the extra wire on each pack ( a positive and a negative) to your connector for the speed conroller and voila! you now have the same thing as one big 12 cell pack. It gives you more volts with the same amps.

If you wire them in parallel, it give you the same voltage but twice the amps, (easier to fry expensive controllers)

Hope this helps

if my memory serve's me right...paralell will give you longer run times....but less voltage...(ex....(2) 6 cells 3300 gp wired in (p) will be 7.2 v ...but 6600 mah)...where as you take the same (2) 6 cells 3300 Gp wired in (s) it will be 14.4 v but 3300 mah.......the 1st one will give you less Volts...but longer run times.....the secont will give you more Volts...but shorter run times......did I explain it good enough.....also if you were able to see the pics i sent you...I made my own chassis.......if not here is the thread link to pics of my emaxx on the forums here.....

If your running the 10XL on parallel packs, wait till you series them up.I have a Novak HV-Maxx and on twelve cells it scares me sometimes

I got my 4200's today, i tried it out just on 18/70 gearing and it SCREAMSSSS. This was done in series, on 16 cells, i might have to get an XL somtime soon though, the motor was running hot, but ill just have to see once i get my strobe (16/51)

Syl, is that the HV? Mine was hot ALL the time...

nice pics, NICE chasis sj!!!! Nice truck, way better than mine!!! I may go to series wiring...I want more speed!!!!

Neweuser, thats with my 10L/9920 combo. It really flies!

ps big daddy, yes that helped. Definately will reconfigure my wiring!!!!

Syl, How hot does your system get running that 18/70? I'm gonna be runnin the 16/51 with the strobe

The motor is around 130f, too hot to touch, but its because i am geared too low, at top speed i feel as if it can go faster, i dont know if ill be able to handle it! I too, will be geared 16/51. I figured it should be the perfect gearing for my application.

neweuser...thanks for the comments...I've been building on it for a few years.....it takes time...I'm sure with time and UHEM ($) it will be the way you like it.....

Really what i need is: Chasis, diffs, tranny...i should be set.
