my son wants to modify my grand daughters pick up truck power wheel

these things are powered by two motors that look like emaxx size motors..they use a 12volt battery...some of the guys on that site series two and three batts together

we are wondering if you could use lipos like we use or nimhs batts to power these things?

Sure why not. I power mine on 3s lipo.

how many 1...... and you using your 700 or 750 motors?...any other mods for the drive train

through tw0 700HO's in there and an MMM on 4s lipo. then later upgreade to brushless. oh wait. do you still want your daughter alive?:lol:

Stock motors, no mods. It is an old jeep, I think it may have been a 12v model.

Don't know what "how many 1" means.

he was asking if you were only running one 3s lipo, which I asume you are only running one right?

you are correct sir

john....do you get better run time from one 3s lipo then the stock 12 volt bat?...and is it a lil faster?

I'm sure if you found some way to find larger RUBBER tires, and not plastic ones, the stock power would be plenty, no?

Good question, in my experience modding my son's you can't fit tires large enough to make a real difference in speed. I ended up bumping my son's to 18V and it makes a nice difference, may even try 24V one of these days.

what kind of batts you using

I would think that the plastic wheels act like a "slipential"...saving the drive train....rubber would grab too good for the plastic drive train parts

imo

I've always found that intriguing.. They slap on plastic tires, that never wear out.. Huh

I guess 24V + Rubber Tires + Bump = Nice Big Bruise

Good point, but hey, they make a lot of noise.. Guess the little kids like that too. :yes:

What kind of controllers do these things use? Are they capable of 24+ volts? I might snatch a couple controllers out of these things and build a bicycle. Is there a way to use our hobby ESCs in conjunction with the controller/reostat that they use so we don't need a reciever?

there are guys putting three 12v in series making 36v

There is no controller in them. They either use a simple switch, or in some cases a relay and switch setup.

3s is about the same as a 12v lead setup, and runtime depends on the packs used. A 10ah lipo will run twice as long as a 10ah lead, because lead acid capacity is determined by a 1/10c discharge.

The old 4ah 10C enerland packs I have, I run in 2p configuration. 8ah gets better than 45minutes of runtime with my butt on there, and enough punch to pull a wheelie if I am not careful about leaning forward.


Generally these things are not run over 18v. Typical vehicles are 6v now, so guys that are running three packs are running 18v.
