I keep up with all the battery and solar tech as I have a direct interest living off grid. I noticed the batteries available on Amazon have dropped in price nearly 80%.
Something is coming and soon. I have never seen LiFePo batteries so cheap. My first 100 watt hour batteries were near $900 each. Now, they can be had as low as $110.
I saw an ad on the Roku YouTube app for a sodium battery based power-to-go thing. Maybe it was from Peak Energy (Colo. based company). I’ve got a vid running in a tab from
Two Bit da Vinci ( https://www.youtube.com/watch?v=FPCaq-Him0Q ) who of course has a promo link as well.
