    I imagine one would have a motor controller that included something along the lines of a variable frequency drive (VFD) and a boost converter for something in the 4.5KW range, which would largely mitigate the issue and open up the door to using a small forklift battery as the foundation of a motorcycle.

      I’m not aware of any BLDC ESCs that implement boost conversion.

      Looking it up it seems such a circuit would be beefy indeed when built to handle the amperages of propulsion.

      Controlling the voltage coming out of the battery is already done using pulse width modulation, but this can only reduce the voltage, not increase it.

      There’s little point in boosting the voltage to achieve higher top speed, as configuring a battery pack for voltage is very easy.

      To the point that I’m here lamenting that PEV designs are upping the top speed even when utterly unnecessary.

        I was joking, yout silly potato. The forklift battery thing was supposed to be a tipoff.

          Why would there be anything wrong with a forklift battery?

          A battery pack is a battery pack.

          Drop an /s next time.

            Forklift batteries are also ballast. They’re lead-acid and weight 600lbs at the minimum. It’s a comically bad idea to use one for a personal vehicle.

              Thanks. I’ll go ahead and file that under “obvious common knowledge” going forward. /S

              I know how lithium packs work and how to program a VESC. That’s all.
