ZeroEm said:Some reason unknown to me. Have been focused on a two speed. So have been thinking about dual voltage system (sounds craze to me too.). Currently ride greenways and with regular bikers at 15 mph. Then less often ride the roads outside of town and with roadie bikes which is faster 20 -28 mph.
Have been thinking about having the option of switching from 36v to 72v. This would keep me in the best range for each task. My current controller can't do 36v, the Phaserunner can. My current batteries drops (splits) from 72v to 36v currently with a flip of a switch. (use this only when connecting the battery currently)
Then there is the settings not matching the battery voltage. And would worry about staying in balance. Would not want to switch back and forth during a ride. The only reason for me to think of such is that the greenway riding will get better w/km and keep my motor from running the 35-50% range. At 36v would be max out at 17 mph and 72v would be 33 mph. Don't think I will do this, just need two different bikes. But there it is, comments?

Then we are back to the topic of energy density, which is the solution that will make obsolete such redundancy, complicated design with 25 times the moving parts for the purpose of saving power usage.
Can a person run at 36v but with double the amps of 72v?
