Ego Powered Power Wheels

So I wa pondering what to do with my extra Ego batteries that I don't really need to use at the moment and came up with an idea. My kids have a Rollplay Audi R8 6v car that them and the neighborhood kids play with. How cool would it be to convert the system to accept a 56V Ego battery!? I took apart my 530Cfm leaf blower just to see the components inside. Found that the brushless motor is inside the vortex tunnel. I think this would make for a fun little project. Perhaps Ego would be willing to donate a leaf blower body (no battery, no nozzle, no stand) as well as a second 56v brushless motor? Haha. I'd use a motor on each of the rear wheels, try to use the variable speed switch for faster or slower driving, and integrate the boost button into the steering wheel to be like a nitrous switch. Who's for this!?

Would be easier to drop down the 56v to 6v and use the cars already existing safe circuitry.
Unless your goal is to make a fast buggy. Then a good electric motor shop can either re-wind your existing motor for higher output/voltage or match something up.

Yeah buddy. My kind of topic

So you will need a voltage reducer. Down to the volts ya need. Then wire it up. Keep in mind it's kids on the vehicle so make sure you have circuit breakers and fuses in the wiring. Also make sure you have s voltage cut off installed. I have gotten a few on eBay that monitor the voltage and cut off a circuit breaker when voltage is too low. Otherwise them kids will drive it down to nothing.

Reducer.

Battery voltage monitor

I set my daughter's up using Ridgid batteries.

Oh and don't listen to me.. I do not recommend doing this. It's not really safe to be honest.

But it will work

Try starting with something that spins slower than 20k RPM. You'll need a heckuva gear reduction unit to keep your kids from going airborne! :-)

Yeah. You can't use that motor. The only one you can use is probably from a string trimmer. They are left and right motors in there so you will need BRUSHED motor or you will lose hi low speed. But who cares right. (The woman in charge will)

So, I did this, and it works great... Until the Ego battery won't take a charge anymore. Anyone else run into this? The battery light just flashes red.

That's not really that low. When you push the button, does it flash a series of codes or just fast flashing?

If you have another battery, use it until its life turns red, not flashing. Then use it to bump the voltage of the other one. Then disconnect them, and quickly put it on the charger. It may only take a few seconds to get it's surface voltage higher so the charger recognizes it.

Clear as mud?

Makes sense. I have a variable voltage step down that I could use to do the same thing, right? The "dead" battery has a solid red light when i push the button.

Oh.. well that means it's just at 15% or less. So if it won't charge then that is a different story. If it flashes red on the charger, then I don't know what is going on. Try a different charger I guess. Possibly the bms in the battery is bad

Ahh.. I have 3 chargers (two of the grey ones, one black) nothing happens when I put this battery on either. So I shouldn't try your charge method?

No. Don't do that. It's not a charge method. It's to bump the voltage up to allow the charger to see it. I wouldn't recommend doing anything. I have revived batteries before but not ones like this. It doesn't make much sense what is going on. Possibly post a YouTube video and post the link. If the battery flashes red when you put it in the chargers, then I want to see it
