agm battery charge issue
what would cause a AGM battery to reduce its charging amperage, without the voltage reaching the set voltage cutoff in a CC mode stage of a charger example, battery is at 13.6 yet a pd9245 in boost...

If the PD output is 14.4 and the battery terminals are 13.6 as measured by the same voltmeter.... there is resistance in the connection between the two. Could be the wire, a connection, fuse, breaker, switch, relay etc. Keep poking along the path until the differential is found. Clean, replace, repair or adjust that item. Some difference might be normal but 0.8 volt seems big at less than 45 amps.
if that was the case how come when i put a load on it, it drops to 12.8 and the full 48 amps from the charger is going into the battery at 570w vs 198w at 13.6 plus whatever amps equals that
