Hi Derek, My current employer (no pun intended) has in one chamber an ancient Edison Nickel-Iron battery it used to run equipment off. These days they use a small (by comparison) analog PS. However... if anyone in your neck of the woods have electric forklifts or golf carts they might loan or rent you some batteries that would do the job.
