I'm sure this is probably a super basic question, but here goes:
I'm bringing back ~120A @~14v from alternator (via blue sea charging relay) to auxiliary battery in the rear. I'm building a compartment for my sealed AMG, but I still want to vent it to the van - 12v .1 amp fan, to run only when battery being charged. What relay would be recommended for such an application? I figured I'd find something here for the 120A rating, but I don't see anything that high. I've also read that really you're rating is in regards to the power, this being all DC, just VxA. Even so, I don't see the ratings in Watts, just amps, so not sure how to select proper relay.
Or... do I need something different than a relay??
thanks,
Erik
