Batteries needed
I am probably reaching the end of the life of the batteries in my FW and boat. I currently have 2 size 24 dual purpose batteries in my FW and I have noticed the useful charge in them has diminished q...

Flooded wet cells are around a 2 bucks a watt hour
Lithium about kilobuck a watt hour..... So no I'd not go with Litihum (Someone posted a "Sale price" a couple days ago.. After I changed undies from looking at the price I calced the cost of my Deka G-20s)
Now.. there are many considerations.> Weight (Li's are light)is a biggie. Height in what I'm about to say.
your G-24s are about 75 amp hours each and you have about a 20-25% usage limit so 150/4 or 37 amp hours (I truncated) is all you can use
GC-2's run around 220 amp hours give or take a bit (My G-20 Dekas are 230) and you can use HALF.. when you put two 6 Volt in SERIES you add volts. not amp hours so you are left with 110 amp hours or about 3 times the power of your G-24s
The GC-2 class is taller but about the same footprint and pricem, as the Group 24 so if you have the head room Give 'em a try
L-16.. Taller still about 450 amp horus and again a TRUE DEEP CYCLE you can use half..
Now I mentioned weight.. For all of the batteries I mentioned except LI.
Watts/Pounds = Constant
That is when you go from 150 amp hours of G-24 to 220 of GC-2 you gain weight. Go from GC-2 to L-16 it doubles.
Dunno where you are buying Lithium batteries for a thousand dollars per watt hour, but us mere mortals are seeing prices in the $10 per Amp hour, which is to say, $1.20/ watt hour.
