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 been taking my time with this project's enclosure, the woodworking aspects, and just last night I got most all of the wiring done. 7 fused circuits, and not a lot of room in which to run their wiring/cabling.
2awg on the PD9245 outputs was simply not going to happen. No Room for it, and as there is only 3.5 inches from PD +output to battery (+) and ~ 11 inches from PD to Shunt, 2awg would be rather insane.
I screwed up one GTpower watt meter when replacing the 12awg aluminum leads with 8awg, and almost screwed up its replacement, but tested it before hooking it to 12v and was able to remove the solder bridge.
The replacement surprised me by actually reading accurately down to the sub 0.1 amp range (compared to my sears clamp on meter) where as my other two watt meters just go blind below say 0.18 amps and are increasingly inaccurate below 0.4 amps.
The Shunt provided with my Drok Combo Ammeter/voltmeter was bent on arrival, and the center section, which was painted black, the paint was flaking off and it appeared to be rusty.
The 'rust' was not rust but more like heat damage from when they joined the center section to the Ends. Not sure of this, or the shunts construction, all I know is it is 100 amps and 75MV.
I took a file to the ends, and where the holes were drilled and tapped were raised significantly Any ring terminal would not have been making full surface contact. It lost most of its silver hue when filed flat and wetsanded to 600 grit, and is now brass colored instead of chrome colored. I repainted the center section with black appliance epoxy.
The Shunt is going directly on the battery (-) and is serving as the (-) buss.
I hope it can read currents of less than 1 amp more precisely than in my initial tests.
The Lifeline GPL-31XT battery resting voltage, well I am not sure what it is. I had removed about 6 AH from it over a week, and voltage still remained over 13.12v on three different meters
Last night, I left the PD on it overnight in a pendant forced the 13.2v storage mode( actually 13.34v) and this morning forced 14.4v( actually 14.56v) via the pendant and amps quickly tapered to 0.45, where as 0.65 amps is the 0.5% of capacity at absv which lifeline says is considered fully charged, So back to 'storage' mode
The 400 watt PSW inverter powered my 6 amp makita hammer 120vAC drill, but I could trip it by grabbing the chuck while spinning. The watt meter registered only a 465 watt surge when the inverter tripped. This was with the Inverter provided 10awg alligator clips. It will have a much shorter length of 8 awg to the battery when completed.
There appears to be a little delay of the drill trigger when powered by the inverter as opposed to the grid. My newer dremel also has the same initial hiccup on the inverter that does not exist on grid power.
It is neat watching the wattmeter show different amperages and wattage at different dremel speeds and at different bit loading.
Anybody Know how much A Vibralux fender guitar tube Amp consumes at max volume playing Jimi's version of the star spangled banner?
Any guesses? I might have some answers soon if the 400 watt inverter can actually power it.
