@swss12 Well, they're not *that* hard to find, but yes, they are expensive. But if you think that's bad, check out the batteries. I spent twice as much for batteries than I did for the motor. Put another way, the cost of the batteries is equal to the cost of the motor *plus* the cost of the controller.
Google American Power Sports for cart supplies. Also of some interest to you , wires, there are spacers for the Azusa wheels to widen them out for wider tires, those things you use are awefully narrow for the weight they carry.
Haha,in secret I have been looking for an Electric Cart Motor :) That acceleration looks AWSUME.........!!! And BURN-OUT'S till the Wheels-Burn-Off. Muahaahahaha "giggle"
Hahaha, yep-very expensive.......as far as leakage-it would be a gas. Don't let anyone fool ya, that gas is TOXIC-Knocks holes in each and every cell it contacts. Weather by skin contact, or vapors. And it really has a pleasant smell :) Very lite (protect with fiberglass) Don't short out,,,,,cause the meltdown is intense. Gell's are VERY GOOD, only heavy.
Ahhh, very nice!! I see you chose GELL cells :) Would be alot more nasty in a crash with regular acid batteries. Try lithium battries (so much smaller) and so VERY expensive-but last much longer :)
Lithium batteries are a lot more dangerous if the contents are spilled, actually. But the real thing that keeps them out of reach is the cost - about 15x more.
Whoa, at 72 volts you will need a helmet and leather jacket. Trust me on this one. You will hit speeds up to what a 250cc shifter kart can! Are you using an Alltrax AXE7245? The bypass resistor is unecessary. Just hook the contactor's contacts on the M- side on the controller and motor, so the controller will still have power, but the motor can still be disengaged in emergency situations.
You are the wind beneath my wings. I checked tracking info, and the parts have been delivered to my front porch. I might sneak out of work early today.
I'm waiting on the bypass resistor that goes across the contactor terminals. (That gives the controller some power even when the contactor is open) I'm also waiting on a 72v contactor, but if I have the bypass resistor, I can work with the contactor I have for now. I'm making the battery interconnect cables tonight. That's it - it's really that close.
is it that easy to break regular lead acid batteries? Or are gells really necessary?

where do you get those big DC motors?? they are hard to find on the internet and expensive as hell

Heavy indeed. This kart sports about 300 lbs in batteries alone. Yeesh.

@XRayCam where you can get those, they are expensive but yeah last forever

Looks great! Any plans for an off-road full suspension electric kart? I'd love to see that!

Thats really good. Cant wait to see it going. Ay idea of how long it will be till you post one with power.

Thanks for the kind words. I can't wait to turn on the power and see how it does. Then we'll really know whether it's any good or not. :D

that looks really great!!! what do you still have to do?
