I've got a cargo trailer w/30amp 120vac. I'm adding a size 24 battery to power a 12v water pump for a sink only, no shower. And a winch. I'm trying to figure out if I should get a converter, battery charger, or battery tender?
This is a competition BBQ trailer that will be used about 36 hours at a time with occasional use of the water pump during that time and maybe 3-4 minutes of total use time on the winch. While trailer is in use it will be connected to shore power.
Help is appreciated!
Charger or converter?

If you only use the 12 volt while you're on shore power you would only need a converter and no battery. If you want the battery you would want a smart charger that would keep the battery charged while you are on shore power. Since you are plugged in so much of the time it does not need to be a large charger. A smart charger will charge the battery and act as a battery tender just too maintain it when it's not in use.
