Bulk-Absorption Charging Voltage
2 Concord 8D (258 AH each) Freedom 25 Inverter-Charger (130 amp) Trimetric 2025 Gauge I'm dry camping and charging my batteries. They were 30% discharged. My Concords call for 14.2-14.4v absorpti...

It also looks like that charger has a similar profile to the vectors... voltage continues rising to the setpoint WHILE amps taper... Not your typical cc/cv profile, where all the voltage rise occurs before amps taper.
joraz, voltage will start out at just enough to get charging happening. So if the batts are at say 12.4v, 14.4v is not required; maybe only 13.4v, depending on circuit resistance.
Make sure to zero out your trimetric's Ah count after charging. You may also need to change it's setting for charging efficiency from the default setting.
