They seem legit, I've certainly seen much much worse and best of all, they aren't a "Johnny-come-lately" hop on the bandwagon lithium player - I see they've been at it for a number of years, long before Tesla stirred a bunch of pump and dumps to get into bogus lithium and/or graphite plays with their battery mega-factory announcement.
Good luck to you.
