I am starting my electrical portion of my build and am not sure what to buy to keep my 12v battery alive. I am not running much 12v. Led lights, 2 computer case fans and a phone charger or 2. perhaps a car radio. I am planning on running shore power to a power bar with an overload fuse on it. From that Ill run my 110 stuff and my battery charger. I was first looking at the battery tender plus but then for a few bucks more i saw the genius 3500 and it seems to have allot more bells and whistles. I will be mainly camping with power hook ups but im sure i will go a few days now and then with out a plug in opportunity. I read that the maintainers will not charge a battery that is out of juice but instead just keep good batteries good. I used allot of technical words there i know.
Long and the short of it does this mean ill have to pack an actual charger as well?
