Re: Charging 2 different battery types
Good feedback. The Golf cart batteries would be a no brainer if I wanted to stay with flooded long term. The drawbacks there for me is that my battery bank (and the only place to really put it) is in the port side lazerette, and I already have a weight problem on that side of the boat, in addition to the short term cost.
Another concern I have on flooded is that the current fiberglassed in battery box arrangement seems to have the batteries in the wrong orientation for healing over. Seems I read somewhere about the orientation batteries facing port or starboard was not ideal.
Long term, I think lithium is where I want to be, from a weight perspective and from a usable capacity perspective. 3 grand is just a lot to drop right now when I don't have the rest of the charging system to support them. My thought is to upgrade to a good short power charger, add solar, evaluate needs on an ongoing basis, and eventually swap to all lithium. That will solve several problems for me. Weíre trying to be very minimal on our power needs, so the most bang for the least amount of space and weight is appealing.
i think just spending $150 on a cheap flooded battery and making due with my pseudo deep cycles will hold me for a while. I probably wont go more than another year on the current batteries.
Iíve got a lot of other high dollar projects/upgrades going on right now (new sails, deck hardware upgrades, etc..).
Maines article posted above was great. Very enlightening.
