Adding a second battery

I just had a quick question and maybe someone can help me. So my idea was hooking up a second battery to my yj and then adding a kill switch to the second battery so I can only use when I need it and then turn it on in case I need to jump it and then I can kind of "self jump" it. My question is is that possible and how would I go about doing it.

get a properly rated solenoid and mount it near the aux batt. run a switch to the dash. energize solenoid from te aux batt. when engaged, they run is parallel. switch off, its isolated. use properly rated welding cable and lugs plus leave slack for engine flex.

this sort of shows what i mean and how i set up mine


edit: well not really. got the solenoid from wrangler NW power products. manual switching on/off is a good thing. others use a tap into the oil pressure to energize aug charging circuit, but i like the fully manual option.
