I see that the Lifeline GPL-31T Deep Cycle AGM Battery is rated at 105aH
Cold Cranking Amps
68 - 880
32 - 750
0 - 600
I have a Northstar AGM. it is rated at 90aH
77f -930cca.
I have seen this Northstar gobble up 75+ alternator amps when cycled to around 50%. The alternator belt was stretched and out of adjustment range and was squealing when over 1500rpm. My voltage regulator allows 14.9v, so it was maxed out. Have since installed new belt.
Since you are limited to 14.4, thats a half volt less potential. I would assume with the difference in CCA numbers between the two batteries and accounting for the capacity difference,
Well I think you might have to to some voltage pot twiddling for the first 10 to 15 minutes with 2 paralleled cheapowatts. I'd be interested if they start buzzing at 36.2 amps like mine did.
Perhaps give it a half hour of 13.2v, then dial them up to just below the buzz once more. I was shooting for 14.7 and pot twiddled upward for max amps just under the buzz until battery reached 14.7, then twiddling downward, and the cheapowatt terminal was well over 0.25 volts higher than battery, but my wiring was undersized for the task.
