[PUP] Passage of Time Batteries

[Alan]

Carl asks:
I'm curious about the battery bank.  Is it one large house bank with
separate starting batteries?  What kind of batteries are you going with?

The main and wing engine will each have separate AGM start batteries (the
main is a 24v, but the Kubota wing needs a 12v for its starter).

The house bank is located forward under the guest cabin queen bunk.  This
allows the batteries to stay cool, but because of the location requires AGMs
(or at least non-venting batteries).  We wanted to have the flexibility to
run the airconditioning at night without disturbing a quiet anchorage with
generator noise, so we have a bunch of batteries.

Arild found some Meridian AGM batteries that used half the space of a
conventional 8D battery.  The AGMs will also allow deeper discharges and
quicker recharging.

We will have 16 Meridian NSB210FT batteries up under the front queen bunk.
Each 12v battery has 209 AH capacity, so at 24 volts we will end up with
1672 Amp Hour capacity.  Most everything on board will be 24v.

The details of the Meridian NSB210FT battery can be seen here:

There is an interesting article, which helped us in making the selection,

The boat looks great!  I'm curious about the battery bank.  Is it one large
house bank with separate starting batteries?  What kind of batteries are you
going with?
