You can see the tiny batteries I'm using at the bottom of two pictures. 12 volts each, about 7 ah. Only 3 of the 4 batteries work. But I got it rolling with 36 volts tonight. No throttle grip. I haven't wired up the controller yet.

So now I'm about to wire the throttle and controller just to test it out, but I want to use the same proper wire. Where to the gauges come in handy? I was thinking 3 ga wire for the controller/battery connections. Is that too much?

Also, I went to Lowes looking for some wire terminals for the throttle group. What terminal sizes will work with the Alltrax 7245? Am I even using the right terminology?

I did a test and hooked up the controller and throttle and I couldn't get it to work. No light on the Alltrax LED. I had it hooked up to a good 12v battery. Any ideas?

And a video of it running here:

I believe that's only 24v it's running on.
