Solar MPPT and lithium batteries
I switched my AGM batteries to lithium's. I can't get a definitive answer on MPPT charge parameters, except to "user define" which I have done. My question is: since MPPT chargers rely on voltage drop...

It's not that lithium batteries' voltage doesn't drop, it's that it drops much more gradually until the battery is almost dead, when it drops like a rock.
