2s x 2 lipo at full charge wont smoke evx?

[cartronicshn]

i just got my first emaxx:mrgreen:, i want to run the stock evx and titans for now, i want some speed and was thinking lipos, yes, no , maybe?

As long as you got the evx with the LVD you should be fine.

 

[cartronicshn]

nope, this is the older emaxx, the low voltage doesnt worry me much, just add a lvd, i am thinking that initial volt output from 2 fully charged 500mah 2s lipos would be to much for the evx, but i tried it for about 15 minutes and it ran great no magic smoke yet:mrgreen:

 

[Rocklobst3r]

Yea, it still works fine if you add a LVD yourself.

2 2 sell lipos are 14.8 volts which is way below the 16.8 limit on the evx's

 

[cartronicshn]

how about running one single 3s packk? which side gets the batt pack plug and what side gets the bridge connector? i think i read that one side only supports up to 7v or something along the lines of this:???:

3s wouldnt work, as you cant hook 11.1v up to one side. and if you split it, it'd still be 11.1v

stick with two 2s batteries. You'll be fine.

And FYI for the jeep guy. 2 fully charged 2s batteries will chime in at 16.8v

... The EVX2 will handle up to 5s with out any issues. The mAh doesn't mean a thing, except run time...

And there is a way to run one 3s pack. You have to make a jumper. Take a connector and loop the wire so it feeds back into its self.

You can run LiPo alarms, or get a Novak cut off.

yes i read somewhere on here that you need a jumper, but i think it was specific to one side , something about one of the sides not supporting more voltage than the other, no completely sure on this:?:

First off, let me apologize for not informing it´s the older evx esc, not the evx2"thumbsup"

14.4v max volt according to spec.

i am pretty sure i read somewhere in here how it was done with a jumper, i could be mistaken.

That is true to a point, you want to jump the non BEC side, unless you have an external BEC. In that case it doesn't matter which side you go to.

Doh! As far as the older EVX, you are on your own... I know if it was me, I would try it. If it blows, it blows...

Id stay away from 2x 2s lipo's then.
That ESC is rated for 2x 6 cell stick packs.

It may run, but no telling how much it'll take at the higher volts.

I'd try and find a new ESC.

Heh, yea Im slow.

We would run 2x 7cell nicad packs on the EVX back in the day with no issues.

 

[Countryhandyman]

2-2s lipo's at peak will be 16.8 volts, they are 7.2 nominal, 8.4 peaked apeice. I run 2-10,000mah lipo's in my emaxx with the evx-2 and one titan 775 from a summit, never had any problems with it.

 

[Countryhandyman]

I noticed afterward that you said EVX not EVX-2, this is rated 12 cells nominal, they mean nicad/nimh not lipo. The old 6 cell stick packs peaked out up close to 9 volts, (1.5v per cell nominal x 6 cells = 9 volts) so 12 cells x 1.5 volts nominal = 18 volts peak. In theroy you should be able to run 2 peaked lipo's (16.8v combined) without issue, just pay attention to the lack of LVD. Good luck
