I see someone arguing both sides of a fallacious argument. How can you criticize one manufacturer for unknown future problems who uses known technology, while lauding unknown technology for a long lifetime that none of it has even passed through? We have all sorts of empirical evidence with small cells. MTBF behaviour is well characterized. But there is absolutely NO empirical evidence for "15 year lifetime" of "solid state electrolyte and synthetic Graphene" cells. Personally, I prefer nickel-iron cells. But I'm an outlier. :-) Jan _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
