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 did think of you Pnichols when the PD had mysteriously dropped out of Boost and went into 13.6v 'normal' mode. The depleted Lifeline was still accepting 37 Amps at 13.6, and pressing the 14.4v boost button on the pendant again only raised amperage by 5.5 amps which is the limit of the PD9245 in my observation/ measurements.
I would not be able to accept a 13.6 or 13.8v maximum voltage of your parallax, and I'd personally not buy batteries specifically to make use of an old outdated single stage converter, but there is more than one way to skin a cat, and we can argue over the effectiveness of that skinning, without end or conclusion and without affecting the other's opinion.
Mating battery and charging source is wise, but if the charging source is limited, I'd not limit my battery choice.
I hear good things about Full River batteries, but only by people who have not had time to run a set through their lifespan. Most just say they are 'just fine' and only have a voltmeter and limited understanding of how a battery ages anyway.
All they really know it the batteries still meet their capacity requirements and are quite proud of that , and love to use the words 'just fine'.
One such Full River owner has a low opinion of Lifeline AGM as a friend o f a friend's wife's neighbor's cousin's friend had one which needed a professional 'reconditioning' after a year of too little low and slow solar, and they did not just outright warranty the improperly recharged battery.
I am impressed greatly with this Lifeline battery, not only in my 50% load test, but in the design of the terminals. Unthreading that silicon Bronze automotive post revealing a beautiful low profile silicon bronze female threaded mating surface below, with apparently an epoxy holding it in place instead of a heat pressed seal, is truly confidence inspiring.
I really wish the T-1275 came with such low profile terminals, it would simplify my intended mounting greatly.
The removal of the automotive post will allow my to mount the lifeline battery on its side, reducing height of the powerpack and increasing its ergonomics in intended use. I pulled the PD off the battery at 0.8 amps and 14.56V, because I needed to see if these posts could be easily removed.
Now, about 22 hours later the OCV is 13.23v
They used red thread locker on the threads.
Here is a pic of thick walled 2awg ring terminals compressed with my harbor fright hydraulic crimper and reground Dies. No ears!. All 8 tons of clamping force compressed the Lug properly:
It might even meet ABYC standards, once the adhesive lined heat shrink is in place. The 2awg is tinned marine wire from genuine Dealz. Pretty flexible for 2 awg. Way more flexible than store bought 4 gauge SAE.
