Does anyone know of a good AGM that fits in a GC-2 foot print, has about 240AH capacity (4 batts total ~480AH @ 12V), and is easy to buy at a price that won't scare most people away.
Lifeline GPL-4CT batteries will give you 440 AH at 12 Vdc, but they're not cheap at $299 apiece.
Still, the best decision I ever made was to substitute Concord batteries (Mil-Std version of Lifeline AGMs) for the OEM Gill flooded cell batteries on my helicopters. Instead of replacing every 12-14 months, I was getting 5 years per battery. Even though the Concords cost nearly twice as much ($840 vs 475), I was coming out way ahead... not to mention eliminating maintenance downtime. When it came time to replace the two OEM Trojans on my Roadtrek, I didn't hesitate a second.
Powerstride had the best prices last year when I purchased my GPL-4CT-6s at $250 each (free S&H), but other sellers may be more competitive today.
