GC8s from sams for around $100 are 135 AH (20 hr) so using .3 as a multiplier gives ~$310 / kWh. Obviously 6v batts are cheaper/kWh but there's no way I'm putting that much weight in my bug.
It's already 1:3, with 5x the life
Depends on what lead batteries you compare to, overcharging the crap out of a 48v 250ahr pack of Greensaver Lead silicone batteries I am still at roughly 95% summer time range over 7000 miles, that includes 10 100% DOD's 50 80% Dod's and lots of little ones (less than 50%).
Now that its warmer my father is racking up miles on his Miles ZX40 again.
The gel batteries do not seem to be affected by overdischarge the way some floodies are, I would estimate the lifespan on this gel pack is going to be in the 5-10 year area assuming it doesn't castrophically fail all of a sudden.
I guess from what I am told 7000 miles off a 48v lead pack is considered good, maybe there are some better lead solutions out there?
