Sidewinders with 4s Lipo

[Ced RC]

Has anyone tried running the Sidewinder with a 4s lipo?

I have two Sidewinders on my clod super, currently running a ThunderPower 3850 Extreme V2 3s and I have a 4s 2200 Extreme V2 I would like to try. I know the Sidewinder states 15 volts max, but considering the application isn't high rpm I'm hoping it will be OK?

Yes, since winter time, with the red wire pulled and a CCBEC. No issues so far. I even threw in a 25T Holmes Handwound with the 4cell, talk about wheelspeed and crawl....Sidewinder is happy as can be.

Is this still in brushed reversing mode, yes? Just wondering if i should be switching to high power brushed for a 27t on 3s LiPo in my buggy.

Cheers, Paul.

Thanks Tanis, I'm gonna give it a go. I'm also using the Castle BEC, red wires pulled, dual 55t lathes. I like having the wheelspeed avail when I need it.

'Officially' the Sidewinder is only rated up to 3S LiPo (11.1V). I was wondering about running 4S myself as I want to run A123 packs and they are lower voltage/cell than conventinal LiPo. I wasn't sure if a Sidewinder would take the 13-14V they push out though, I tohught the Sidewinder and Mamba Max were only rated up to 12V but in fact if you do the math, it's rated at 14.4V on NiMH running a 4600 motor...

This evidence is kinda encouraging however, is it worth trying a 4S A123?

Well I tried a 4s lipo in my super tonight, wow the wheel speed is insane!
After some tweaking of the throttle curves I think I got it where I want it, great smooth low end control and crazy high end wheel speed. I need to take it out to the rocks for the real test though, I'm sure the battery life will be shorter as I was using a 3850 3s and the 4s is only 2200, the battery life will be more than enough to run a couple of courses though

Ced RC can i get your exact setup info ,is it Clod axles 55 lathes, twin Lipo or single?

Thanks!!

Thanks!!

Clod axles, alum gears, TTR CVDs, Integy 55t lathes, dual sidewinders, Castle BEC, one ThunderPower Extreme V2 4s 2200 Lipo. Also see this post:

Just watch the heat on it and you should be OK. I have ran 4s on my sidewinders many times.

Thanks John, I will be using a temp gun (infrared) to monitor the temps. I want to do some testing on the rocks to see if the extra wheel speed is beneficial, if it proves to be even slightly beneficial I may stick with 4s, if not I will be switching back to 3s.

I see the SW is rated for 12/8 cells running NIMH batts depending on the motor but those are brushless.

What would the limit be with a 35-55t brushed on nimh?
