LY has seen with AGMs (me too) that after they get down to "end current" at 0.5a/100AH and you leave them at 14.x volts they will keep warming up and that takes more amps, so amps start going back up. Time to lower the voltage!

You and LY need to use temperature compensating chargers that automatically roll back Voltage and then Amps cannot run up.
Of course you can hang around observing while your batteries charge, or use a shutoff timer if you don't want to hang around.
My Solar chargers and my inverter/charger both automatically calculate the Absorb time and charge Voltage.
But you guys run for the garlic and holy water when any dares to speak well about anything automatic. :)

The idea is to get down to 0.5a/100AH at 14.4v (77F). Temp comp for the voltage is fine, but how can you get auto for when amps get to 0.5a/100AH? You do not roll back the voltage until then.
