Firefly's Oasis Group 31 batteries getting some EV fans excited {Autoblog Green}

Jan 31st 2008 7:48PM I am not doubting that the power output wone be better and maybe charging and life expectancy.. that said.. 100aH for 70lbs.. thats no better than AGM UPS batteries. Powersonic PS-121000 is 100 aH at 68.9 lbs. I thought there was supposed to be a huge savings in wieght?
