Hi all. Currently messing with various EV powertrains in a cheap Amazon minibike before committing to a street-legal conversion.
Bought a VEVOR 48v motor+controller combo. Very amusing. paired it with a 5ah battery I built out of a Honda Insight 5ah 12s lithium sub-pack. I then bought two 19.2ah orange batteries and a Kelly KLS-N controller to see how much better the performance would be. Hooked it all up, got it spinning and calibrated, but it cogs like MAD. Weirdly the cogging is worse in one direction than another. After googling it looks like the cause is/could be the hall effect sensors are slightly advanced in one direction.
Not even sure if "cogging" is the right word. It stutters extremely bad going CCW, and going CW it runs smooth until over 4000rpm and then it stutters in a similar manner to an ICE car rev limiter.
So my options are, as I see them:
1. Attempt to 'fix' the motor by relocation the hall sensors. ($free? but i have no idea what I'm doing)
2. New motor. Golden Motor BLDC-108 perhaps? ($168)
3. New controller. This guy on Youtube has the exact same motor, throttle, hell even batteries and connectors as me, but he's using a Kelly KVD ($120)

Any other insight or a best route welcome and appreciated.
The eventual goal here is for a powertrain that I can transfer into my Suzuki FA50.
