A motorcycle is too limiting for easy change of a motor, so I started looking at Karts. I wanted an offroad kart, but they take up a lot of room and I'd need a...

    Sevcon model compatibility

    Hive mind, So I know that part numbers ending in 203 for the Size 6 80V models are compatible with Motenergy motors (Sin/Cos). I know that the part numbers ending in 201 are not (only do AB or Hall??). From another contact, he said a Size 4, 80V ending in 310 is NOT compatible with sin/cos...

    OpenEVSE build

    I got the OpenEVSE last year and totally slacked on building it. My Brammo came with an EVSE, so I had very little reason to build it. Decided to finish it up this last week while it was rainy. Very easy kit. It's flexible enough such that you can spend as much or as little as you want. I went...

    3000W Battery Discharger Project

    I've finally gotten back to my discharger project. A while back I aquired 6 Darlington pair modules (400A/600V) and matching heatsink from a buddy of mine. I figured I had most of what I needed for a high-power battery discharger. I followed magudaman's 1000W discharger build and emailed John...

    Advanced DC XP-1283 Specs?? Anyone?

    They did the same thing with my K91 motor.... 91 is the year it was designed. They're VERY responsive. I've emailed them about 4 motors now, and they haven't failed me yet. What kind of ftlbs of torque? how much does the motor weigh? 4-brush or 8?
