I was checking out these Lithium Ion batteries that Red Poppy Ranch is upgrading on his homestead to. LiON technology is the future but it’s still very expensive and somewhat experimental with limited equipment for off-grid homes compared to traditional lead-acid 6-volt batteries which are more common. But LiON doesn’t require nearly the maintenance and can take a reasonable amount of abuse. Cool technology for sure. I look forward to seeing a video of them when he posts it.
