Hi everyone, I had just been doing some research and surfing the internet on the new Lithium Ion type rv batteries. Only by chance did I come by this site New sulfur-based battery is safer, cheaper, more powerful than lithium-ion | ExtremeTech
It is a short but very good read as to the progress of new battery technology. Maybe one day we will have a 1000 amp/hr battery that only weighs 10 lbs (LOL)
By the way, in the lab tests, they are burning out the sulfur cathodes prematurely, so if any of you have an idea, this could be your fortune and we could all benefit by having a long lasting and cost effective battery in our units.
