Dual battery or booster pack?

No different than anything else that a motor maker specifies.

Ok to use non OEM products "IF" they meet specifications.

"IF" the Relion battery continues to meet Mercury's specifications then it "should" be OK.

Ok, ordered a mini ACR rated at 65amp. My alternator is 65amp. Now would a 4awg cable to the ACR from the house battery be ok? Or should it be 2awg, like the starting battery is? I will draw maybe 30amp from the house battery.

Your ALT will rarely output full amps, and you said it's 6 feet (double 12ft). So using double that and it's non-critical 6 awg will be plenty and 4 awg is even more

Thank you.
