http://kellycontroller.com/kds72200e200a24v-72v-mini-brushed-controller-p-762.html Debating on going for this controller, since it is smaller, lighter, cheaper, and still 120a continuous. I'm not sure if the hit down to 200amps for 1 minute is worth it though. The kelly website says for...

Okay lithiums are looking to be way too dangerous and expensive for me to handle. I'm settling for some UB12500 s because if I run them at 72v I'll have around 40 miles range with 12hp continuous and 30hp max. Weight of the entire battery system will be around 200lbs but that is only a...

Okay thanks for the insight. I think I might as well go big or go home.`If I go for a set of 72v lithium ions and get a real controller purchased, what would be my best/cost effective options. Everytime I go searching for lithium batteries I end up browsing alibaba pointlessly. Can someone...

Hey guys so the controller specifications says it can handle 50v, but only 36v of batteries. I do not see why I cannot put 48v of batteries though. As my battery choice I think I am going with these: http://www.pepboys.com/product/details/838838/00469/?isPayInStoreOnlyStore=false If I run...

No problemo, decided to pull the trigger on the me0709 after talking to the guy, should be able to fit my needs. Once I get it I'm going to see if I can test the osmc on craigslist to see if it works. Otherwise I guess I'm off to wait on ebay :/

Ideally I'm going to shave down the motorcycle to look like this to save weight. The majority of the heavy weight is from the heavy motor, which once removed should make the motorcycle adequately light enough. Thanks for the more info on the mars 4201, but is there any ratings on horsepower? I...

Hello all, I am in the process of building an electric motorcycle out of a 1988 kawasaki ninja zx600-c. This is one heavy street bike! On craigslist I found a OSMC that I was thinking of using. It says its only for brushed dc motors, but I've also heard that brushless dc motors work as well...

Hey so I am in the process of planning the build for my own electric motorcycle. I was looking at some walmart batteries, which are marine deep cycle batteries. They have an excellent AH of around 120 ah for only $100 with a free 5 year warranty. The issue is that they weigh 60lbs a piece, so...
