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...

the charger does all the charging. period.
Exactly, unlike PWM, MPPT is a more sophisticated dc-to-dc type charger (utilizing surplus voltage), but no need to be concerned by that - just set the charge voltage at 14.x volts, but not to exceed 14.6v… Float (say, 13.6v) is unnecessary but nor will it hurt, and forget equalizations…
