I connected the charging port of the new Dometic lithium battery (PLB40) to my auxiliary battery (Optima YellowTop) and then connected the output of the Dometic battery to my fridge. I was careful to make sure the power cable is secured so that it can't get pinched in the fridge slide (have heard some stories about that). With this configuration, the PLB40 battery pulls power from the YellowTop until it is depleted. Then the PLB40 powers the fridge (up to a full week) until the PLB40 is depleted, too. Then when I start the Jeep using the cranking battery, the auxiliary battery recharges (via the Genesis solenoid system) and the whole cycle begins again. Any issues with this set up? I found an article that says different types of batteries can't be connected in line, but I'm only connecting the charging port of the PLB40 to the YellowTop. And my understanding is that the YellowTop is a deep-cycle battery made to be drained and recharged up to 400 cycles.
Thanks!
