Hi all, I'm just barely getting my feet wet on this whole EV thing, but I've been gathering and scrounging parts for about a year now, and I intend to convert a 1993 Kawasaki ZX600 into an electric, short range (10mi daily round trip) commuter vehicle, and I've got a motor from my work's old forklift, a Presto-Lite, approximately 8" diameter and 10" long, and also was given a bunch of extra parts like the original GE EV-100 controller, and quite a few new spare brushes for the motor, etc, but where I am currently with the project, I'm seeking direction on switching to a used or refurbished Curtis controller from eBay, or a new Kelly. My budget is $250 or less for the controller, so a new Curtis is out of the question. Assuming the bike ends up at 350 pounds, 525lb with pilot, what amperage of controller should I be looking for? Top speed can be approximately 40mph depending on the route I choose to take, I'm sure I'd prefer to be able to hit 55mph, but I'm willing to concede for the sake of not buying gasoline at all next summer if I can help it haha. I've been looking at about 100 different Curtis controllers on eBay, all capable of 48v, and the variety is just making my head spin, so if any experts could chime in and just narrow down my options that would be fantastic! The one Kelly controller I was even considering is this one, but I've heard some bad things about Kelly so please just help me straighten out what I should go with. Thanks in advance!
