    So the ME1003 is VERY similar in spec to an Agni 95R?

    Ok. Damn. Didn't know that 95R would do THAT!

    Controller & battery pack suggestions?

    Based on this chart @ 60V it can draw ~365A @71rpm/volt

    I would get something with about a 1/3 margin. so 450-600A range.
    depending on how many batteries you run and what you charge them to get a 48v or 72v controller. I kinda like the new ones from alltrax. They seem slick.

    I can't quote it directly, but there was a thread I was following back in the day that had an AGNI motor, which I believe was the same one. It was almost identical specifications: Similar RPM/volt, approx current handling, torque constant, etc. There were a few variants for agni motors, but I'm pretty sure on this.

    After building that car, I must say... I really love LiCoO2 batteries. The iron phosphate are simply too heavy, especially for a cycle in my opinion. Hobby LIPO continues to be highly competitive, but I think it's finally at the point where Nissan Leaf modules are edging out - especially when you consider ease of wiring and balancing fewer packs. I'm going off of people's reviews on this website. All I know is my Hobby LIPO has so little voltage drop, it behaves as though it were a higher voltage pack under load.

    Basically.... it all depends. If you go all out on the battery pack, even if you pick lower current rated cells, it doesn't matter when the current is shared by enough batteries.

    Ok, so a 450-600A controller for a brushed motor. Check!
    Would it be better to run 9 Leaf cells at 8v/ea for 72v total, or 10 Leaf cells at 7.2v ea?

    I'm not sure what your range goals are, but 10 leaf cells probably aren't going to cut it if you want to much highway driving. That's a little under 5 kWh.

    For reference, Zero motorcycles list their battery pack size and range expectancy:
    Zero SR model: Nominal capacity 11.4 kWh, 161 miles in city, 98 miles highway.

    Voltage determines your top speed on a brushed motor
    Current = torque

    The higher the voltage you pick, the more torque you can extract through the RPM range capability of the motor.

    AGNI is a very small motor. I'd be weary of it for sustained highway driving > 55 mph.

    I see. So, Jayls4, what motor could be swapped in for highway driving?

    (What's nice is that no appreciable $ has been spent thus far...)

    Good, last thing you want to do is blow money without research.
    As a point of reference my ME0913 bike has a 5KWh chevy volt pack. 24 cells, 52ah at 88V nominal 98v peak. I can get up to 80mph max on the highway with the motor spinning at 5000 rpm.
    on the way home i only get up to 70mph b/c the battery voltage is lower. the gearing is 16T front 72T rear. With that pack I get 40-55 miles. The faster you go the shorter range you will have.

    Only $ spent thus far was the $300 for a clean titled '10 Zero S.

    Your specs sound like they'd work for me. Can you link some photos por-favor?

    Looks like the ME0913 is almost identical to the ME1302 other than the 1302 is liquid cooled. I was thinking that could be the smarter option since I live in New Mexico...

    Ok, give it to me straight: Is this Agni 95R any good?
