It's easiest to explain this with a diagram.
I'm simply thinking the controller is a switch that either completes the circuit or opens the circuit.
The controller still sees 24 volts...but the motor sees 48 volts.
Can someone explain why this will not work...I must be missing something.
What if we put in more batteries? The controller still only see 24 volts, but we can let the motor see 72 volts or even more.
It feels this should also work even for brushless motors like our favorite Xtreme bikes.
