I'm with Mike. Lead is NOT dead!, yet. Not by a long shot.

I'm about to start my ninth season with my 8A4D AGM 48 volt battery bank and they seem to be holding up well. I'd like to get to ten years and so far it looks like I will. As you mentioned the type of boat/car use may influence what batteries are most cost effective. I have a 30 foot SAILboat the EP system is truly auxilary propulsion. Though I can operate in hybrid mode with my Honda 2000 should I need too. After seeing how my AGM's are holding up and how Lithium prices have not come down as much as I thought they would. I probably will repower with the AGM's since my boats charging infrastructure chargers/solar/wind are setup for AGM charging. It continues to work for me and as they say "if it ain't broke don't fix it" :)

Well, 2 years ago I bought 8 6v GC2 golf cart batteries, 220ah, from Sam's Club for $85/ea. So $680 plus core and tax for a 220ah, 48v or let's see... 10.56 kw/hr. so call it $64.4/kwhr. Lithium has a lot of advantages, but for getting a foot in the door cheaply, the golf cart batteries are the way. I simply could not afford Lithium, period.

I think one reason LEV builders favor lithium is the energy density. More kw/hr per pound of weight. Weight is not as much of an issue in a boat, generally. For a land vehicle the weight penalty when climbing hills or stop and go (well, the go part, anyway) is a significant impairment. So on top of all the other advantages of lithium, for wheeled vehicles, there is the weight issue as well.
