So I gather that you actually need a controller to go with the charger? I just need a charger to keep the batteries up while the unit is stored, as I'm unable to keep it plugged in where it's stored. I could remove the batteries & keep 'em charged at home, but that's such a hassle. How many volts (from the charger) do you guys recommend? Trickle charger, or something between 1-12V? More voltage than that?
Terry, I'd like the specs on that system if you don't mind, thanks!
