Preacher, I have a Lester summit 2. I was not able to use the open space in the battery compartment opposite the controller because I use an separate 12 volt auxiliary battery to run all my extras. Cart batteries are for running the cart only. So I had to make some slight modifications with a little bar stock to fit it in the cart. I also removed the male end of the charger cord and fitted it with an outlet made for use on RV’s and motor homes. All I do is throw an extension cord in the truck when I take it on a trip.
