I good strong charge is good for a battery, it stirs the aid up. Never run your trailer on just batteries unit the lights are getting dim, as you are way below 50% charge and damaging the batteries. While you have 220 AH, only 110 are really usable without damage to the batteries.

Here is a good start in learn more about batteries. There is a part two also.
