PD9245 and Lifeline GPL-31XT testing
I just acquired a Progressive Dynamics PD9245 converter to specifically charge a New Lifeline AGM GPL-31Xt at 125AH capacity. I tested the converter tonight on a different battery, and saw Voltages...

I've got the Powerpack 98% finished. Just some minor details to work out.
I depleted the Lifeline gpl-31xt battery ~68 amp hours last night in my rig, and voltage rebounded to 12.34v in about 2 hours and stabilized.
After crimping on the terminals for the Burly 500 amp winch connector(2awg) We carried out the beast (~ 95 Lbs), to the 2013 Ram powerwagon, whose Alternator I cabled with about 12 feet of 2 awg to the connector. The powerwagon had 4 Gauge (SAE?)to the alternator, and I just added the 2awg to the (+) output Stud. I ran the 2awg ground cable to the battery (-) as it was en route
After the high Idle slowed down, I flipped the Manual 300 amp continuous Blue seas On off Switch to ON.
The 100 amp Drok voltmeter/Ammeter combo just started blinking a 100.1 Amps, and by the time I got my Clamp on Ammeter and returned, this had tapered to 98 amps.
My clamp on Ammeter read within 5% of the Drok Ammeter.
5 minutes later 88 amps and voltage had only rose to 13.2v.
The Hottest spot on the alternator I could find read 220F.
I was surprised it was capable of such high amperage at Idle speed.
Amps kept tapering, but only to 84, but volts were still only 13.2v.
More RPM did not increase amperage. I think the alternator is protected against overtemperature, as the Lifeline could obviously take more at 13.2v.
We then carried the powerpack into my workshop and plugged it in. That battery read 12.8 when the PD was plugged in.
The PD9245 maxed out at 45.5 amps, and it started automatically in 'Normal/13.8v' mode.
I pushed the 14.4v Boost button anyway.
5 minutes later, Max PD amps tapered to 42.5, then 40.1 as the unit heated up and battery voltage rose
This battery is impressive.
