    They're made for an EV, so it's going to be something like 2-3000 cycles 100% which would give you about 80% capacity at that point.

    Get some Leaf batteries and go have some fun. They're easy to wire up, and fairly known as far as charging and voltage high/low limits and current ability. If they were around when I converted my...

    Motenergy's graphs are a bit non-standard. What they do is set the motor to run at a certain RPM, and then gradually load it down. It's not a standard torque vs. RPM curve. They only load it down to...

    3 motors, 2 of them are a Dual Stack in one case going to the rear diff. Front is a single motor going to the front diff.

    1 motor per inverter, so 3 inverters.

    I've been in it, but the driving has lately been for testing at race-speeds and I've not been part of the testing crew. I'm just the electron-herder.
