I fly a lot of R/C models ranging from turbines to electric powered helicopters. The chemistry in the batteries has changed over the years but the highest output batteries right now are lithium polymer. Now, there are some A123 type batteries that are better and getting better but most of the extremely high powered aircraft right now use Li-Po.
Battery failures can be caused by several things but what alarms me about putting something like this in a vehicle is the hazard of fire in the even of an automobile accident. When you have a high impact with some of these batteries and a cell is ruptured - the packs begin to puff - then vent. When they vent, the heat is thousands of degrees which will set off other cells in the pack.
Think of the old stories about exploding gas tanks in the event of a car crash. Now think of all of these batteries packed into tight places under trunks and back seats and getting rear-ended or even just a cell going bad...or the balancer in the charger going out and overcharging a cell causing failure in that cell. A failed charger can cost you your entire car...or better yet, your house. Think of this thing going up in the garage...and you having a gas water heater installed out there.
This stuff is dangerous enough as it is right now.
