I personally do not like those plastic boxes... They tend to get brittle with age (a hand full of years)--In my experience.Also--I worry about fire (shorted cable catches the plastic box on fire)--There are some advantages to plywood (slower burning, maintains shape when subjected to heat).-Bill
You are aware that those are NOT deep cycle batteries . . .
These low cost, high quality wet lead acid batteries are
ideal for photovoltaic, attended applications.
These small 6 and 12 VDC deep cycle batteries are the backbone
of any autonomous power system and will deliver up to 1500
cycles at an 80 % depth of discharge.
12V LEAD ACID, DEEP CYCLE SOLAR BATTERY - 115 AHR
Not going to bother to call the salesman about these batteries . . .Have a look at this pdf I located. . .DC31DT is a Deep cycle - flooded lead acid batter
I am with you Skippy, on this. Looks like the Deka DC31DT Is a true Deep Cycle battery, also look at this selector guide:http://islandwaterworld.net/iww-files/pdf-description/LeadAcidBatteries.pdf
On that Selector, starting batteries are noted as Starting, Dual Purpose are so noted, as are Deep Cycle batteries.
One of my pet nagging points has long-been, that just because a battery manufacturer happens to list MCA, CCA and Reserve Capacity, that does not necessarily mean that it is just a Starting or Dual Purpose battery.
Some manufacturers like Surrette, list CCA, MCA and RC of essentially all of their Solar batteries, none of which are Dual Purpose or Starting batteries.
Here is an extreme example:http://rollsbattery.com/wp-content/uploads/specsheets/2YS62P.pdf
That is a 570 Lb, 4860 Ah 2V battery with a CCA of 11,480 A, a MCA of 14,350 A, and a Reserve Capacity of 16,386 Minutes ... IMO this is probably NOT a Starting or Dual Purpose battery.
A number of manufacturers simply list just about anything that a buyer or user might want to know.
Looks like a nice start on your system Skippy.
Not to try to put too fine a point on battery types ... Cranky Vic
mike95490 said for a small battery, that is a large cranking amp spec
There is generally no problem with this, providing that allowance is made for the lower cranking amps
compared to a similar size starting battery. As a general rule, if you
are going to use a true deep cycle battery (such as the Concorde
SunXtender) also as a starting battery, it should be oversized
about 20% compared to the existing or recommended starting battery
group size to get the same cranking amps. That is about the same as
replacing a group 24 with a group 31. With modern engines with fuel
injection and electronic ignition, it generally takes much less battery
power to crank and start them, so raw cranking amps is less important
than it used to be. On the other hand, many cars, boats, and RV's are
more heavily loaded with power sucking "appliances", such as megawatt
stereo systems etc. that are more suited for deep cycle batteries. We
have used the Concorde SunXtender AGM batteries in some of our vehicles
with no problems.
It will not hurt a deep cycle battery to be used as a starting
battery, but for the same size battery they cannot supply as much
cranking amps as a regular starting battery and is usually much more

Me too Bill.The understanding that most deep cycle batteries (except the Surrette Marine and others) are not designed for vibration.If vibration is an issue, then it does not matter how big your deep cycle battery is, it may not survive a diesel engine near by or bashing into 14' waves.
I am available for custom hardware/firmware development

a new refrigerator was delivered.
Good Night....all this discussion on how to "hop up" freezers and refrigerators almost makes my head hurt. My gut feeling is there exists an excellent chance that changes could backfire. Or should I bravely surround my 2016 Danby freezer and 2004 Samsung fridge with mondo insulation?
Skippy, er the charging... you have not mentioned if you made it to float, the settings for Absorb or Float. Especially how many hours of Absorb they get... this is where a MidNite Kid or Classic with a WBjr shines...
