    Haha! You're welcome. It's fun and I can remember a lot about how my build made me feel, even though I never got to V2.0.

    Good luck!

    Would that individual be me? :)

    It's a great setup I've used on a few builds, and sold to multiple customers. It's pretty easy to set up and wire. You made a good choice.

    This is exactly my fear. A partnership seems better than buying the motorcycle brand like they did with Brammo.

    I actually got a job working for Cascadia Motion, so I basically put my project on hold, and I think due to Corona, Topkart has put this on hold as well.

    They were from a US recycler of batteries. As far as I know they don't ship internationally. I found him on Diyelectriccar.

    Yes, they're not straightforward to do yourself from my experience. Not unless you have experience. I'd order a matched pair motor/inverter. Otherwise you could spend months of work getting it to...

    Yes, as long as you get it paired from where you buy it as a kit. I'd say order from Thunderstruck, and make sure that it's the right controller for your motor.

    I haven't heard complaints, but it's the holidays. It's been busy for the EV Industry. Just keep on them.

    What inverter are you going to use with it? That will be important too.

    I think that you should get a paired motor/controller combo rather than try to get individual parts like that and doing it yourself. I don't know of any file that exists for the 1305 motor for the...

    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.

    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.
