Each time when accelerating I was...

The max discharge rate according to the datasheet for the batteries is listed @ 300A, so I was thinking I could do so without damage, and really thought that maintaining a higher voltage with a 60A...

You were right, that is actually how I wired it originally, I just got in too big of a hurry doing the diagram and didn't actually look. I assumed I'd done it the same, and didn't. Sorry for the...

I do have this pic from a few weeks ago. It's after the 2nd sprocket (right side) was added, I'm checking alignment of the 2nd motor and deciding how I'm going to mount it. I'll take more though.

I honestly don't know. I don't have a way to weight it. I'm out of town right now but should be home on Wednesday. I'll dig out the manual (before my mods) and see if I can find a weight listed.

First run results (48V 1800W on a large kart)
