lithium ion car and motorcycle batteries

Lithium cells are a great power source. Very low weight compared to lead/acid and Nickel/Cadmium. There are many types of "Lithium" batteries. Unlike the Lithium Cobalt Oxide, which is used in the Boeing 787, the Lithium Iron Phosphate are somewhat safer. We have done extensive testing of the Lithium Iron Phosphate cells and battery configurations in a lab setting. We purposely shorted the charged lithium iron phosphate 26650P cells in a safe lab environment. Temperatures of 600C (1100F) were recorded! Please be careful with connecting several batteries in parallel. Proper buss bar sizing and insulation are critical. If you go the lithium route, one battery is safer. All tools that we used to work on the lithium cells were Plastisol coated in case one was dropped onto terminals. Once again, Please be careful using these batteries! If you go the lithium route, verify and replace any bad wiring, floating grounds, prior to installation. If these Lithium batteries get over discharged, they become bricks. If these batteries get overcharged, they become fire hazards. Hopefully(?) the internal safeties negate any of these issues. You will be spending big $$ for multiple lithium batteries compared to one lead acid battery, and have major safety concerns under the hood of your ride just to save 25 pounds of weight.
Good Luck, be ultra safe.
Seen below is the 787 battery that went into smoke mode. Last I read, there was NO red X that was identified as to why cell #6 went into overheat which lead to adjacent cells going also.
