re 12v vs 6v Batteries
Extremely strange to read all the opinions re this subject. Most written by author "OLDMAN" I purchased my new Wildwood last month. The contact person that did the paperwork was a "OLDMAN". In my co...

You are WAY better off with 2 6 volts batts and no I won't explain why. Just trust me.
for many applications I agree. There is one that I believe 12V will be better. That application is when the dominant use is with a high power inverter (1KW and up) or other constant high current draw (>50-75A). Then 12V banks are IMHO a better choice. They offer low voltage drop with high current, and with more banks for the AH needed, each bank is also supplying lower current.
But if your draw is more like most 12V appliance draws then yes 6V is the way to go, even if you occasional have a high current draw.
I disagree.. You take a pair of six volt 225 amp hour batteries and draw say 100 amps off them, that is 2/5ths (40%) of their 20 hour rating, (Of course modern six volt are 230 but I'll stick with 225 for now cause that's what mine are. (older)
You get say two Group 29's, roughly 100 amp hours each and while it is true that each battery is only providing 50 amps that is a full FIFTY PERCENT (1/2) of their 20 hour rating. So again the six volt win
Group 31's. you have a total of about 260 Amp hours. But only just a bit better.. 5/13ths of the total capacity..
But Group 31's won't fit in the same tray.
Though that said: Starting batteries are designed to deliver amprage that EXCEEDS their 20 hour rate, That is a single Group 24 can easily deliver more than 150 amps (2x it's 20 hour rating) for a short period of time.
But it can also only deliver about 20-25 percent of that power before it begain to suffer big time, where as the six volt pair can deliver half their power before they really need a recharge.
