Since much of the posts I've followed lately deal with Battle Born Batteries, I found this factory visit by Will Prowse, his observations and opinions interesting. Also I followed with a link to register for his solar forum which has no advertising.
I have followed Will since he was homeless, disabled, living in a van, living in a Bounder, bought a home in Las Vegas and now on his You Tube Channel, DIY Solar Power with Will Prowse. I was one of his early subscribers, now numbering over 200,000. He now owns his house in Las Vegas, owns a Tesla, hasdifferent solar systems in his home and makes $35,000 to $50,000 month off of the web and publishing books. He has been a good teacher in helping me understand solar and electricity better. He, along with Roger of the FT forum have gotten me to where I am now. He gets paid nothing directly from Battle Borne.
