True, but they are longer end-to-end and do not fit where the 4D goes. I
have glassed in supports sized to the 4D.  I would definitely have done that
and saved my back if they fit.

Also three group 24s fit into an 8D box if you have one.

2 type 31 AGM batts will give you 200 amps and are far easier to move than
the 4D

Subject: Stus-List New Batteries Last Time I Buy Lead 

 

I have been trying to put off buying new batteries until I can rewire for
Lithium, but that was not to be. My last sail saw the house battery drop to
about 12.4 volts an hour off shore power and the engine battery struggles
with a cold engine.

To my surprise, the local West Marine in Annapolis started carrying Odyssey
batteries. I got a 4D Odyssey that uses their pure lead thin plate
technology. This is basically an AGM, but is supposed to have a longer
lifespan and charge faster than the conventional version. The West Marine
branded batteries are really East-Penn Deka batteries. The Deka AGMs are
only "OK", not great. I was really happy to see WM branching out a bit. For
the start battery I decided to risk a battery made out of Chinenesium, if it
dies I am not out a lot of money nor is it hard to change out.

There are a lot of U1 size AGMs on Amazon, most of them seem to be around
150-170 CCA. This one is 320 CCA, which is plenty for me, the A4 starter
draws about 130 amps.

 

I am 100% sure the next house battery I buy will be lithium, getting a 120
pound battery into it's spot was a huge PITA. Right now the tech is just not
there on the cheap end. The "drop in" batteries really are no such thing.
They might not blow up or catch on fire, but they may have a vey short
lifespan depending on exactly what they get dropped in to. Even worse is
when on a dark and stormy night the BMS decides to cut off all your power
for some random reason.
