Emaxx lipo battery options

[Addict Rc]

So I got my hands on a emaxx. Which would usually use 2 nimhs. But I want to run lipos. So should I run 2 2s? Or does it even run lipos?

Yes, you can run two 2s LiPo batteries. But the brushed E-Maxx typically runs on two 7-cell NiMH packs, which are 10.5v max each. Whereas a 2s LiPo is 8.4v max. So you will lose a bit of power going from 21v down to 16.8v. Our Stampede runs faster on NiMH than it does 2s, but it won't when I swap the motor to a brushless setup.

awesome thanks. If I were to go brushless what combo are you going with?

For running lipos depends on the esc and motor. And also depending what voltage they can handle.

Battery brands:
Zeee, hoovo, CHNL, SMC. There multiple out there that are good. @Greywolf74 is our battery tester and recommend-er

Personally I'd go with 8bl150 G2 from hobbywing.

Oh @Addict Rc
Your back!
Long time no see

Yeah I have a ton of different lipo brands (basically all the same 2S’s with different labels ) just wasn’t sure if the system was capable with lipos

3906, the old ugly black ones I dont think have lvc. The 3905 with tge Grey chassis, I think the first versions were not and the later ones were lipo cutoff.

Novak used to make a low voltage cutoff. Maybe you can find one or someone else may.

You might want to get chassis and tranny parts. All the other parts are still on the tmaxx and avaliable.

Congrats on the beast. I always wanted the emaxx vtwin.

I have the gray chassis one.

Not really sure what version it is, traded a propane fire pit table for it. It works but the battery’s are smoked and I don’t want to buy more nimhs

Your esc does mot appear to be. The one I linked says low voltage detection.

Nice ride. I always wanted that model.

Ah dang. I’ll probably pickup some nimhs then. Just gonna get it going because we’ve got a few sand pits in the area I think it’ll rip in. Might as well get it going now since I broke my finger and can’t ride for the rest of the month

In my opinion, until you go brushless, you might as well stick with NiMH.

Alright cool. I think I will then

Would this be workable @WickedFog ? The trx esc is 100-120.

With the brushed motors, I would think it would be ok. Is that, 80A x 2? Only guessing based on the model number.

But if the plan is to eventually swap to a single brushless motor, I think I would just wait to buy a standard ESC/motor combo.

So theoretically speaking you can’t do dual brushless right? Thats what my stepdad wanted to do but I told him I don’t think you can.

The traxxas vtwin was an emaxx concept with two 1/10 vxl 3s esc and motors. To do it you need to cut or pull the pin on one black esc wire to reciever. Because traxxas got with castle over the embe tells me it wasn't efficient in some way.

The video by yoyomany2k is traxxas' video. It was done around 2007 or 2008.

Just make sure they are the same motor and esc and gearing. I would get new combos on top of that.

For the record I drove my tmaxx on single vxl 3500.

You can, but there is no need to. Unless you are going so fast that wind resistance, gearing, or weight is keeping your motor from reaching its max RPM (in which case the motor would overheat anyway), adding a second brushless motor won't do anything.

So basically, if your gearing is optimal for the motor, adding a second motor won't achieve anything at all.

Looks like a fun spot. Never seen a dirtbike with a phone holder.

 

[Greywolf74]

You can consult this thread to find a spreadsheet that shows whichs LiPos are the best, at least out of the ones I've tested. LINK

Put that on there so when I explore new places I can have Google maps on lol
