Dual 6V battery box
February 27, 2017
by on February 27, 2017

I purchased the battery box to upgrade my 5th wheel from the standard 12V battery that came with it to a dual 6V system. The box I selected was exactly as described on Battery Marts web page. The box showed up on the scheduled date in perfect condition and worked beautifully to contain my new batteries. There was one minor flaw but I believe the mistake was mine. I ordered a mat to go under the batteries inside the box. I assumed (incorrectly) that one mat would be sized to go under the two batteries. I was wrong. I will need to order another mat. Other than that everything was perfect, everything was exactly what I ordered. I am a happy RVer.
