12 parallel wiring best or better?
Which of these two parallel wiring diagrams is right or I guess the better of the two? I guess my question is should the inverter and charge controller be wired to one lead battery or split the positive and negative between both 12 V batteries, newbie obviously. I just want to have the better of two connections, i've had the first battery for about two months and I'm adding a second to it, just trying to figure the best wiring. Thanks.
