Small shunt controllers do not do abs charging, only bulk.
Yes, and that is how my modded pm4b behaves. There is, of course, a point at which amps begin to taper, but it has nothing to do with the setpoint being reached. Voltage simply continues to rise, as amps taper, until near full charge.
It was the line on page 13 that said the battery only gets what it needs, instead of having a higher voltage forced into it, that caught my curiosity.
