I dunno really. If the batteries were new (40Ah), I'd hope for about 30 miles. With used batteries, I'm hoping for 20 miles of realistic driving. Honestly though, I really have no idea. I'll do a bunch of laps around the block when I start driving it to determine what my actual range will be before I take it on any outings, grocery runs, or commutes.

Hey BigMouse. Glad to see you here. You've made some good progress.

I love watching the vids of your milestones. Brings back memories!

Thanks! I'm almost done with it. It's very exciting.

I dunno how long those U/S nicad cells will last you, Mouse, but I guess it's a good (free!) start.

(I work in the aviation industry, and spent a bit less than a year working in a NiCad battery shop... (holy boring job, batman!))

Unfortunately I'm no longer in a position to snag dead cells like that, otherwise I'd probably do the same thing. A friend once got enough cells to build up a small (yet still heavy) pack to power an awesome coilgun he'd built at home. That was fun!

Well, I've given up on building my own controller. Gone through too many IGBT's and too many little chips and mosfets. As far as I can tell, everything should work, and it does to an extent, but as soon as I apply a load, things fry. I'm finally admitting that it's over my head, and am ordering a controller so I can finally finish my project!
