Can you float charge lithium batteries? Should you float charge lithium batteries? What are the best settings for your charge controllers? Will float charge destroy your cells?

I played around with a lot of solar charge controllers trying to understand and find the best absorption and float charge settings. It can be very confusing and it’s a bit hard to fit this all in one video. Please let me know if you want to see more details about a specific setting and how this works out in reality. I will break this down and make a separate video about that then…
