Motor is 3kw, stock volts is 72v. New controller capable of 96v so will add some more batteries, see where that takes me. Controller capable of 80a continuous but cables not beefy enough to sustain that so will limit to 80a. I am used to 3 phase variable speed drives on ac induction motors, these use a combination of waveform frequency and volts to control speed, so assumed the same would be the case with the Sabvoton
