Here are comparisons of two pairs of batteries -each pair exactly the same weight. Each comparison has a pair of 6 volt batteries in series - compared to a pair of 12 volt batteries in parallel. Note that are all pretty much equal. I also added on big 12 volt battery that has equal weight to two of the others. It beats them all.
Note that for a fair comparison, you have to compare batteries of equal weight. Stating that your best expert friend Joe Blow changed his 6s with 12s and does better - is useless nonsense.
First comparison:
BCI type 4 47 lbs. wet weight 6 volt CCA 1000 amps RC 270 minutes
BCI type 3ET 47 lbs. wet weight CCA 500 amps RC 120 minutes
Two of the type 4 six volt batteries in series equals – CCA of 1000 amps and RC (reserve capacity) of 270 minutes.
Two of the type 3ET twelve volt batteries in parallel equals – CCA of 1000 amps and RC (reserve capacity) of 240 minutes.
Second comparison:
BCI type 7D 60 lbs. wet weight. 6 volt. CCA 950 amps RC 350 minutes
BCI type 17TF 60 lbs. wet weight, 12 volts. CCA 530 amps RC 150 minutes
Two 7D 6 volt batteries in series = CCA 950 amps and RC 350 minutes
Two 17TF 12 volt batteries in parallel = CCA 1060 amps and RC of 300 minutes
Also - here is just one big 12 volt battery that weight what the other two would weigh . .
BCI type 908D, wet weight 120 lbs. 12 volts. CCA 1375 amps RC 430 minutes.

Today's Featured Article - Hydraulics - Cylinder Anatomy - by Curtis von Fange. Let’s make one more addition to our series on hydraulics. I’ve noticed a few questions in the comment section that could pertain to hydraulic cylinders so I thought we could take a short look at this real workhorse of the circuit. Cylinders are the reason for the hydraulic circuit. They take the fluid power delivered from the pump and magically change it into mechanical power. There are many types of cylinders that one might run across on a farm scenario. Each one could take a chapter in
