    Yeah, that fuse is essentially the CNN or ANN style fuse I was talking about.

    Pretty good Ted! You learnded! hehe

    Basically, yeah, DC and AC ratings aren't the same. It specifically needs to say it can handle 60VDC or higher in order to use that safely. Another thing, is...

    I don't think you need water cooling really. The ME1507 is a good sealed, reasonably priced motor. Goes good with a Sevcon.

    For battery, I don't know that you'd need more than 2-3kWh if you're...

    They're made for EV's. Used in formula cars and a handful of others. They're fine, i may be going a different direction though... not cause they're bad, but because I need something repeatable.

    I doubt I'll ever do a bolt-on kit for motorcycles. The electrical can be a kit, but brackets, battery box, etc, that's all going to be custom for just about every motorcycle build. One guy wants a...

    One thing to realize, is that the controller max stator amps is 660A. And the 475A is likely battery side. They won't ever be the same. The controller is a bit like a gear converting one RPM/Torque...

    I say Sure. Brammo had a battery plug that could be disconnected while working on the bike.

    Most of the mainstream EV's only use a Contactor (or two). They're spring loaded and usually have a magnet that helps quench the DC arcing. The EV200 and LEV200 I use in my systems can break 2000A at...

    The Sevcon DC-DC I sell is an isolated DC-DC converter, meaning the 12V output is completely isolated from the battery pack High Voltage input.

    Clearview is for the Sevcon Gen4 only, it's not designed to work with other devices and uses CANopen for the protocol.

    I don't know much about their BMS or if it's isolated. Essentially, it needs to be isolated at the cell level, so current cannot flow from B+ through the BMS to that cell.

    I don't know that I'd...
