Charge vs. Float voltage: What if MPPT only has charge?

[Stephen InGeorgia]

Ok, I'm striking out on google search.
What exactly is float voltage? Its slightly higher than 100% state of charge, but less than the charge voltage.
If my AMPINVT MPPT-60A only has a manual charge voltage (no float option) set at 28.4v, do I care for my 24v Lifepo4 battery?

Float voltage is the sustained voltage of the CC after other charging cycles have been completed.

If my AMPINVT MPPT-60A only has a manual charge voltage (no float option)

That unit DOES have float in modes other than Li-ion.

set at 28.4v, do I care for my 24v Lifepo4 battery?

If cycled daily, I would drop it to 28.0v and forget about it.

Great! The MPPT reads about .2v higher than my inverter/charger, with the voltmeter right in the middle. I'll drop it for longevity sake.
