We have decided to change our batteries, and I'm sure this topic must have come up before but it is a minefield of information and contradictions that I was hoping for some help with.
We need approx. 360ah for the house system, and are looking at 2 180 batteries. I have been recommended wet cell lead acid batteries any thoughts?
My other question is about the engine battery.. we are in a catamaran with 2 (new) yanmar 3ym30 engines, currently starting off a 120ah battery which is unmarked but I think it is a deep cycle with low cca. The engines require 70 amps, 385cca 455mca. I am looking at getting a minimum of 100amps but am unsure as to the advantages of having 2 batteries in parallel or if 1 decent battery would work just as well.. again, any help would be greatly appreciated. We are in the Greek Islands and can order the battery we need but the best info I can get off the guy in the shop is that they are all "very good batteries". ..
