Hi folks, im looking at 3 new deep cycle batterys for my 2010 triton. 2 for trolling (24v), one multi purpose for cranking/accesory. I've done a little research and reading and was wondering if the optima batteries are worth the price. Also, is the factory onboard charger (12 amp total, 2 bank) be good enough. Any feedback would be helpful as i have some FISHING vacation the end of march. Thx, Kris
