I've got a Reece breakaway battery on the trailer I built earlier this year.

Like this one: https://trailercamperaustralia.com.a...50-85-320.html

Its got an inbuilt smart charger, so only needs a 12v feed from the tow vehicle to charge it. I've got it connected to the tail/position light circuit on the trailer so I always tow with the lights to keep it charged.

Last time I went to use it the battery was flat. Only been sitting for 4-6 weeks (its previously sat for longer and still been OK).
I'm not convinced the cheap Chinese battery it isn't dodgy, but aside from that I need an solution to keep it charged when not in use.

I can think of a few different methods, but has anyone got a simple working solution for keeping these things charged?
