You could use a reversible transfer pump. Boaters sometimes use them to transfer fuel from one tank to another, but they work fine with water. Most run on 12v. I've seen a few rated for 24v use, but never any (that I can recall) for 36v.
That is a thought, however can a transfer pump provide a nice 30-40psi at 3-4gpm (enough to run a hose and a sprayer to spray off the roof of the shed).
I could go 12v on the pump, however that would be higher current draw and require me to tap the pack. Which has it's own problems.
