24v hub motor on 48 battery

I really enjoy my low profile 24v hub. However, its time to upgrade my battery. The hub may die soon too.. got 3000+ miles on it. Is there a way I can get a more modern 48v battery and still use my 24v motor for now? Maybe upgrade to a 48v hub later? would something like this work?

A motor doesn't know voltage I've controller knows voltage and monitor Only Knows wattage to many watts and it will melt.
Volts × amps = watts. How many watts can your motor take

Motors hit a point in which their efficiency drops due to overvolting. Your wh/mi numbers go up if you overvolt too much.

The voltage converter might work but it will have a lot of loss and be prone to failing. It would be better to upgrade the controller to one that works on 48v and just keep the current limited to whatever the motor can handle.

The main things to remember:

--at twice the voltage, the motor will spin at twice the speed for the same throttle setting.

--you'll probably have to buy a new controller with the battery, cuz the 24v one probably doesn't run at 48 (might not survive being plugged into it). (converters can work, see wturber's thread for going the other way around, but they add complication and range loss and potential failure points, and controllers are cheap)

--At twice higher voltage, the same current limit gives twice the peak power, so the heat in the motor will rise faster for a given current.

--I forget what the other things were... time for a nap.
