Trailer have brakes????
Trailer needs a good charged battery to provide power to energize brakes if trailer should disconnect from tow vehicle.
That is the main reason for the battery.......secondary is providing DC power for trailer equipment when not connected to shore power.
Having a good battery provides a load bank for converter even those converters that can operate w/o battery in place.
Go buy a new battery.....mark cables before removing so that you don't install backwards (reverse polarity) and be SAFE.
