Not that hard to remove that little battery. Put in as mentioned a size 24, or a smaller U2? Mower battery on hitch. Or as I did with my enclosed trailer. Put the U2 in back corner. Not best from a eight standpoint. But at 20 lbs, not as bad as a 24 or larger battery.
Another issue with said installed battery, besides probably not set up for lights. Many trailers like this are sent with a single use battery. In other words, if it gets used in a true break away, or if your being an AH to an LEO and they decide to pull cord and do a check that the battery locks breaks. Then decide to do an equal test later. That 2nd test will fail, you have a failed brake system, a fine, and can't pull the trailer until e brakes work again. ....
Any way, better to out a deep cycle bigger battery on trailer if using the lights not hooked to TV if it's wired that way.
