If you have an RV or Boat, a lot of campsites charge users for electricity. The power is usually low wattage, but it still can be expensive if you’re paying for your charge. Some parks charge by the hour, or by a “delay period”, where you pay a certain amount to delay the billed amount by the length of delay time.
Days of boondocking and electricity drag on, you could be paying hundreds or even thousands of dollars in a month for RV electricity. So, to resolve this problem, Battery Monitors are the easiest way to control your RV battery charge.
