AGM battery setpoints?
Now that I have this nice fully adjustable Rogue MPPT 3048 I suddenly realized that I don't know battery setpoints - Absorb V, Float V and Full I (charging current at SOC 100). Alright, current in...

2 to 5 amps would be the transition to float. Battery decides transition from bulk to absoption.
Yes, for a healthy battery taken out of service for charging.
A battery in service with a 2-5A draw may never exit absorption Volts and incur damage due to excessive Volts. There is no problem with a 2-5A draw at float Volts so long as the charger can do that and keep the battery at stasis.
Is this a manual or timed process to switch to float?
The generic definition for the transition to float Volts is at 90% SOC. What charger actually knows SOC%?
