replacing battery with converter

the trailers onboard converter is long gone. this is a modified hunt camp type deal. the battery just seemed like a good place to tap since it was already there. could be done inside a the panel as well. Don't want a battery because it needs to be maintained. not looking for any charging capabilities just 12v dc on demand. was not thinking rv converters so much as stand alones. I was concerned about filtering the 12v current as well. any idea how to tell what quality output you will get from the specs?

Older converters needed the battery to act as load and help control output

Newer electronic control converters do NOT need a battery.


Trailer stationary.....no battery required.

Fixed voltage output (single stage) converter would work

The battery does act like a large capacitor in the 12V system. I would spend the extra $75 and know that the battery is helping the 12V system. If the trailer does need to be moved, a utility outage occurs, or the converter fails, you'll still have some 12V to power some of the functions.

Yes that will work. Seems odd to connect at the battery. I would connect at the 12v fuse panel. Should also have 120vac power there close to plug in the converter.

When I disconnect my battery, my existing converter handles all my 12v needs.

Yes, better converters like the ones Progressive Dynamics build, do not require a battery in the circuit. Lesser unit require the battery for filtering the DC.
