Is the voltage vs speed relationship basically a straight line? I am

currently running a 48 volt nominal pack and have a top speed of 32 MPH.

The controller is not in current limit at only 120 amps with a constant

current rating of 325 amps. If I up the pack voltage to 72 volts, could I

expect the top speed to increase to approximately 48 MPH? This is assuming

I don't change the ratios and the higher voltage controller doesn't end up

in current limit. The expected controller is a Curtis 1209B with a 1 hour

rating of 175 amps.

I am contemplating going from the current pack of 8 T145s which is 48V 265

AH to possibly a pack of 6 Genesis XE60 which would be 72V and 62 AH. I

realise this would cut my range down to 25-30% of what I have now. I would

look at the XE90s but I am told the lead time is 22 weeks.

respectfully,

John
