I’m being led to believe that when charging two 12v RV batteries that it’s more efficient to (see diagram) run a jumper from batt A Pos to batt B Neg and a jumper from batt A neg to batt B Pos. In many cases I trust the information I get here more than I get from YouTube videos. I’m thinking that if this were true then everyone would be doing it, so that’s why I’m asking.
My current batteries are Duracell Ultra BCI 24M AGM 78Ah model SLI24MAGMDC. Please advise. TY.
