Ok so I stopped in Auto Zone and found 100+ ah deep cycle batteries for under a $100. Is their really that more of an advantage to getting the Stinger SPV70's over these? Like what would the percentage be? I'm having a hard time pulling the trigger on $100+ batteries (wasn't in the origional budget). If I do their gonna be last! Or I could get 2 of these now and upgrade later this year. So many decisions!!! lol!!
