Use case is a heavy cargo/tandem in the mountains, so maximum torque is needed; I likely want to go to higher power than Phaserunner can provide, say 100 battery amps capacity, even if not often used over say 60A.
Speed is not at all important, but range efficiency is **critical**.
From my reading, I thought 48-54V was as high a voltage as I wanted to go.
Then I came across this quote in my past notes:
> The 72v ecosystem is better for going above 2500w
Is that true, even when speeds will not get past say 20-25mph?
Say I figure out a reasonable 5kW motor / controller (+CAv3) combo
( recommendations please! )
Is there any inherent advantage looking at setups that **require** up to 72V or even higher?
Of course, the ideal would be focus on great low-end torque at 52V now, and then be able to tweak up to a higher voltage pack later on to see if I can get a little faster top speed without sacrificing needed torque.
What sort of motor / controller specs should I be looking for ?
