RE:RE:RE:RE:Common groundHey Ticket, VRFB's are longer lasting than LI batteries (ca. 20yrs!), they don't overheat, the V can be re-used afterwards so it's basically infinite. Check out LGO board and they are a producer of diff types of V and vertically integrated for more info...they are a bit further along the road and are going to the Nasdaq in the next few weeks.
