Pull up to your local hobby shop, and get out and tell them "Hey wana come see my lithium car" ? They will blow you off till you say "Hey, no it's not the latest (insert whatever new radio control car they are racing or high performance helicopter they are flying) It's a real car, you can drive "IN" it"
watch out, you will be MOBBED and will need to take EVERYONE in the shop for a ride.
(For folks that don't know, the Radio Control model industry has been completely transformed for years from lithium battery tech, they know more about cell tech then just about anyone, a good fast, high discharge cell to them is better then crack to an addict"
you will be "the man" on the block, trust me.
