So why do all cars and trucks still use Heavy lead acid batteries for starting and lights & accessories? Why aren't they useing Lithium instead? Why doesn't your Goldwing use a lithium? They are not even useing lithium in HYbrids for the electric motor portion. I looked at a Hydrogen car the other day and it has a lead acid battery for lights and accessories! So yes there is a great market available for the PWTC battery! World wide!! All we need is to get them made and the word out. I'd buy 3 right now!
