Decided to change out my batteries this past Friday before the big weekend. Took out three (3) of the group 31 Optima batteries and a Honda generator (generated to much heat) and installed two (2) Discover 4D batteries (480ah total). Wired them in parrallel with 1/0 gauge to a Stinger 12farad cap. Played all day without a missing a beat. Also installed the newer APS 75 with "smart charge" for charging and a group 34 Optima for starting. Here's a few pics.
