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.

Now I have my main fuse panel primary wire going to my starter battery. I should be able to move this to the house battery? The ignition switch is my only uncertainty. Would the start circuit still work? The key switch goes to the starter solenoid, energizes it and the main start battery would power the starter.

If it deals with the motor running it stays on the start Bat, as in key switch, gauges, starter, alternator, power trim, etc



If it's for any other stuff, this can go on the house Bat

Thanks alldodge, I will double-check. I forgot about the throttle.
