Re: [ElectricMotorcycles] AGM orientation

[Mbachandz]

Jody, I'm going to copy this to the list to get opinions from other EV MC folks.   I don't know much about the Hawkers. Does anyone out there have any experience to share about the Hawkers in an electric motorcycle?   My current 72v AGM battery weight is 258#s with 45 - 65 AHs each depending on whose spec you believe. This should produce 4680 WHrs (72v X 65AH). While the Hawkers would produce only 3120 WHrs (120v X 26). Are my calculations correct?    In terms of peak KW of power my configuration would in theory produce ~25KW of power (or 33.7 peak HP) at 350 amps. While 120 volts at 450 amps would produce ~54KW or 72 HP.      What about the charging profile? What chargers work well with Hawkers?   Can you send along the measurements so I can do some rough space planning? Do you believe that because they are smaller that a more creative configuration is possible?     I have been wondering if one went above say 450 (motor) amps (aka Altrax) would it be necessary to modify the standard ADC motor? Also I see where the D&D are supposed to be a bit more stout that the ADC 6.7, but some of the D&Ds are also 15" long as opposed to 10.5". The Warp guys are looking at bringing out a new 6.7 or 7", but not much info yet.   Long story short I am wondering if we would need to have Jim Husted at Hi-Torque do some serious preventative measures if one were to head north of 500+ motor amps in the 6.7" class?   If you are able to get some higher voltages that would seem to improve range, but I have always been under the impression that more amps equals better acceleration (which is my goal). If I were to go up, I would probably just go to 96 volts as a first step and see what the actual results are like first.   - Mike B
