I found that most all of the charging current goes into the battery
with the bad cell. I basically quickly boiled the cell dry and it
gave off SO2 which smells like rotten eggs. I did not notice at first
and did notice the charger working overtime and ignored it. I finally
realized and put it all together when the engine would barely start
even with both batteries switched on. I then investigated and found
that it was just the one battery and the one cell almost dry and the
battery was VERY hot. Fortunately, the other 4D was not yet ruined
and was able to charge. I was away on a cruise, but if I had left the
boat with the batteries paralleled the best thing that could have
happened would have only been the 2 batteries ruined. At worst, the
charger ruined or even a fire.<br>

Re: [C36IA] golf cart batteries and Battery system design</div>

We HAVE been talking about the possibility and risk of a bad cell and
it's implication on paralleled batteries. I have experience with a
bad cell.<br>
<br>
Steve - It is great that this has worked fine for the first 4 years.
I'd be more concerned about the next 4 or 5 years. Bad cells do happen
and you have no way of easily isolating it.<br>
<br>
Jeff - The 1-2 -off switch allows you to isolate a bad battery. Hard
wiring the alternator and charging system to paralleled batteries with
no switch would allow the bad cell to soak up all of the charging
current while still draining the good battery. You would still have
the starting battery to start the engine, but would be unable to charge
with the alternator because most of its output goes to the failing cell.<br>
<br>
Please don't misunderstand me, I do advocate the benefits of on large
paralleled banks, but only if they are monitored and only paralleled
while you are on board.<br>
<br>
I know, I am probably just a little too risk adverse on the boat:<br>
I don't have a PSS seal because I don't want the risk of a bigger
hole in the boat.<br>
I don't have a shore water pressure hook up for the boat. Too many
boats have sunk at the dock this way.<br>
I don't have a mast furling main. I know yours hasn't jammed in
the first 10 years, what about the second 10?<br>
<br>
Boat systems don't usually fail when they are new, but when they are
old. What happens with the inevitable failure?<br>
<br>
Jeez, I'd better watch out or I will replace Miller as the list
curmudgeon. <span class="moz-smiley-s3"><span>;-) </span></span><br>

better approach is a dedicated house and engine battery. A switch in

An automatic combiner relay (Blueseas ACR) can be used to have either
battery charged when a charging voltage is present (e.g. alternator or
battery charger). Furthermore one should also have the alternator
connections bypassing the battery switch altogether and directly
connected (with appropriate fuse of course) to the house bank. This
eliminates the possibility of the battery switch disconnecting the
alternator output current from the battery therefore frying the

I'm an electrical engineer and I've had 4GC batteries hard wired in
series/parallel for about 4 years now. I think it's the way to go. It
reduces the depth of discharge to prolong the battery life. I
understand the arguments against it but there are many very large
battery banks that operate this way. The key is you can not mix
batteries. You replace them all at the same time with all the same
type. As with any issue there are pros and cons. <br>
<br>
Granted, my area is most certainly not lead acid battery technology
(I'm into digital hardware design and FPGAs - small wires!) but a large
series/parallel bank (almost 500Ah) with a separate starting battery
has worked very well for me and I would recommend it.<br>

think that in theory you will divide the load equally between the two
banks. The batteries will not know if they are wired in parallel
directly or through the switch. I say in theory because the batteries
may not be exactly equal and I think that could influence the division
of the load. In saying that I am getting lost in my mind and
considering things that really don’t matter but are interesting to
think about. That quirk of mine drives the Admiral crazy. If they are
not equal, they will be close enough not to matter. </span><O:P></O:P></p>

<p class="MsoNormal"><span
style="font-size: 10pt; color: navy; font-family: 'Arial','sans-serif';">Remember
that golf cart batteries are true deep cycle batteries and can be
safely drawn further than marine deep cycle batteries that are not
really deep cycle. I used to know the recommended safe level for GC
batteries but now I am not sure. I think it was 50% or maybe lower (I
seem to vaguely remember 20%); and that can be repeated hundreds of
times.</span><O:P></O:P></p>

<p class="MsoNormal">Our estimated use is 100amps/day. If I
connected them in series, 2 to a bank, and chose "all "on the battery
selection switch would I draw 50amps from each bank.I am trying to
reduce the percentage of amps taken from each bank.. 50 amps from each
bank would be about 20% of capacity from each bank. I don't want to
take 100 amps ,40%, from one of the banks.<O:P></O:P></p>

would wire the new “12V” (actually 2 6 V) batteries just like the 4D’s
through the existing switch. Then they can be paralleled just like the
4D’s or used individually if necessary, if for example one of the 6V
batteries failed. In rereading your email, maybe that is what you
meant.</span><O:P></O:P></p>

<p class="MsoNormal">Thanks to Gene, Bob & Bill for the
suggestions, and thank you to Gene and Mike for the photo's. I picked
up the batteries this morning so I can now start measuring for the
cables.<O:P></O:P></p>

<p class="MsoNormal"><span>A few more questions:</span><O:P></O:P></p>
</div>
<div>
<p class="MsoNormal">1) Did you use 2/0 cables?<O:P></O:P></p>
</div>
<div>
<p class="MsoNormal">2)I had my 4d's connected in parallel to
increase amp hour capacity. Is there any downside to doing this with
the GC, after they are connected in series.My goal would be to reduce
the percentage of amp hours removed in between charges?<O:P></O:P></p>
