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?
