Wow, I just got a PD9280 for $100! It was on ebay for $180, and I made an offer. Slightly used, 30 day refund.
How many aH total do I need before I dare blast them with the 80 amps, or is the charger smarter than that? I am 1000mi from my big new batteries. I do have one 100aH agm here, and two 45aH gels.
Battery University has information about charging batteries. The battery acceptance will be limiting current from that 80 amp number. The PD charger is smart. It will determine the current delivered.
Also, you'll want to charge those gel cells at a different rate than the AGM's in all probability. Gels are fussy.
