We have a 2008 260 DA with twin batteries and a selector switch. When on the hook, we'll use batt#1 as our house battery for stereo, fridge, lights, etc. and save batt#2 for starting the gen or engine. I'm considering adding another battery in parallel with batt#1 to extend the time that we can remain on batteries (w/o having to start the generator to charge them). I will wire the new battery in parallel with the existing battery and use the same diameter cables; connect the positive (red) cable to the battery post and the negative (black) cable to the ground post on the back of the engine block. I'm pretty sure the battery charger can handle charging both if they get drained down. My question, has anyone completed this or know of a better way to do it? I'd like to get some feedback before I purchase the cables (custom made based on new battery location). Kudos to CSR forum I have found a good source for the cables.
