Want to use EG4 Lifepower4 48v battery for 12v travel trailer.

[Batavian]

I have 8 Lifepower4 48v batteries , my 12v Lead Acid batteries that I was using in my travel trailer are no good.

Would like to use one of my 48v batteries as a 12v, I have a chargeverter I can use to charge battery if needed. Not running any large loads just water pump lights and range hood fan. I have a location and wiring for the 48v battery already set up.

This is a temporary just for weekend camping a couple times a year, tired of replacing Lead Acid battery that fail from sitting unused.

Unsure of what types of 48v to 12v converter I should use, or if it is a dumb idea and I should not bother.

30-60V to 12V, 30A:

The only issue is if you have electric motors that might exceed 30A on startup.

What about a 60 amp converter? I'm planning to do the same but with 24 volts, not 48. Something like this?

Or 100 amp? Is there a downside to a larger amp capacity?
