2 x 12 volts or 2 x 6 volts batteries?
Hi, I am about to replace my house batteries. I was reading that connecting 2 x 6 volts in series will double the voltage but not the amps. Connecting 2 x 12 volts in parallel will keep the same 12 vo...

Not a useful comparison
You can't use (3) 6's in an RV, you need two or four
Two sixes is still only 245 amp hrs at 12v
And two 12's will be from 160>210 amp hrs, depending group size and rating
Cheap grp 24 75 amp hrs each
Good grp27 110 amp hrs each
In many cases when going fla batteries, 6v GC give the best results,
Unless you are planning for heavy inverter loads,, then 12 AGM give better results
One of my 6 volt AGM battery failed, it read 4.2 and the other reads 6.4. I need some batteries to get me going until I am in USA to buy new ones at Costco or Sam, none available in my Costco. I have two old acid 6 volts, still useable but not very strong, that I want to pair with my 6 volt AGM.
I was planning a tempory installation of 3 x 6 volts to get more juice. Two in parallel and one in series with the two parallel, isn't it possible, I am just about to connect the setup!
