Daniel: On my M17 I used a Costco deep cycle wet lead group 24. Was 9 years old and working fine when I sold SWEET PEA. I set up most of the Sage 17s with either wet cell or AGM group 24s. Found West Marine a good option as if any problems can easy find a store for warranty support. On the second SageCat, first production boat, I set up an electrical system that used a small U-1 AGM battery. Was fine for a 3-day 'weekend' of electricity. LiFePO4 batteries are an option but require a new charging system along with battery management if you are replacing a lead type battery. Prices are dropping, reliability is increasing, and if you get the rated lifetime out of the battery are cheaper over lifetime v lead types. LiFePO4 also provided more power in less space and weight. In addition you also need to make a decision on how much power you will use, and how and how often you will regenerate power. I spent 10 weeks on my M17 and using a 30watt solar panel had plenty of electricity for my simple needs (less than 8amps used each 24 hours). :: Dave Scobie :: M6'8" #650 :: Baba 30 #233 DEJA VU :: SV SWALLOW - sv-swallow.com :: former owner M17 #375 SWEET PEA - m17-375.com :: former owner M15 #288 SCRED - m15namedscred.wordpress.com <<-- new site!
