    Definitely possible. SmartBattery has a 20ah 12V battery for about $280. It tends to have a lower ESR than an equal energy lead acid battery so you could live with a smaller ah rating.

    Very interesting indeed. Had not realized these were available for more or less general automotive use.
    Wonder if they'll have to be encased in a special steel container with a vent pipe to the outside of the vehicle? :D

    $37,000 for the bank the same size as mine. About 4 times more expensive than my batteries.

    Sounds about right. On the plus side they should do 2000 cycles.

    I have a small 12V Li-ion for my dirtbike and love it. The bike sits in a shed for months unused and the lead acid battery hated that. The li-ion battery can sit for 6 months without use or trickle charge and its still at full capacity. Its also extremly light. It was a 4cell 12V and was around $90. I think these will be the next big thing for motoercycles and ATV's when the Prices come down. The 8cell Li-ion for my ATV would cost $250 so I'm holding off on that for now.
