Hi there. Can anyone speak to the energy consumption of a finished second generation Probe conversion? I'm looking at building one for my momma for commuting (she has a crazy fear of mechanical parts that can break) and want to see what kind of battery pack will be necessary. Since she drives like a little old lady and rarely uses the motorway, I was thinking (with no real basis for it) that a 72V 100AH system would be good. If she needs to go more than 40 miles she just calls me and makes me drive her, so that's my design limit. I'm shooting for freeway capable, but not too often, and 40-50 mile range. Does anyone have any thoughts on this? If my momma knew I was planning this I'm sure she would thank you all too. Thanks in advance.

Check the garage.

I wouldn't consider this conversion 'finished' but it was my inspiration to start my own:

this will be very sluggish..... and prone to holding up traffic.

I would suggest a minimum of 120v - 100ah lifepo4 (thundersky or calb) with a 9"dc, or 8" at very minimum with cost effective 400-500amp controller like the curtis 1221 or 1231.
