Which battery pack will provide the most :) per mile?
To me, cost per mile of different battery technologies seems to be pretty close if you include purchase and replacement into the formula. So I would like to focus on how much fun I will get out of a battery pack.
I have Giant LaFree with the two 12 volt 12AH SLA batteries. I'm looking at replacing them pretty soon, they were new in 2004 and are getting worn out. I'm probably getting half the range I should out of them.
What I would like to achieve is more power/speed without too many mods. I'm thinking if I can get a replacement battery pack that puts out a few more volts over a longer period then the SLA's that came with this bike, that would do the trick. Has anyone done this? How did it work out?
