All bridges whether competition or low budget will need to be calibrated. If you build it well than the center of mass of your bridge is exactly in the middle. This means you imagine ALL the bridge weight as one side of your teeter totter which is I believe 3" on one side of the fulcrum. The 2 batteries with their bottom 28" from the fulcrum is the other side.

If you can only move the battery 14", then you need a heavier bridge, which means add 2 equal weights an even distance from the center. If you were so inclined, you could measure the actual distance from fulcrum to center, then do the math and figure out exactly how much weight to add.

If you want the dynamics as close to competition as possible, then pay attention to all measurements dealing with the hinges: their distance from the floor (and therefore also their distance from the deck), and their gap.
