You need to measure current draws to find out what's drawing power, starting with the current being drawn from the battery. A DC clamp meter makes it easy, you don't have to disconnect wires and then connect through the meter to measure current.
"After charging all day" tells us nothing. Which name/model batteries? What did you use to charge them? What voltage were they charged to, and how long were they held at that voltage?
I am get SICK AND TIRED of people asking fr help on electrical issues when they WILL NOT HELP THEMSELVES !
Buy a DMM/clamp meter ! There are dozens to choose from on Amazon for less than $50.
The OP is wasting our time without any data.Start by looking at the current draw from the battery and then measure the current draw to each individual DC circuit from the DC distribution/fuse panel. 10 or 15 minutes and you will know where your power is going.
