If memory serves, Lee Hart did something similar with small Gates Cyclon lead cells many years ago. I hope he'll chime in with the details. Years ago, I converted a 120vac B&D mower to DC, replacing the 120v PM motor with a 36v one. I didn't try to use the handle switch for DC - I can't imagine that it would have fared well - but instead used it to operate a small golf car type contactor. The downside of that arrangement was that it sacrificed the dynamic blade braking that the mower had originally, and thus some safety. I powered mine from a 38v 10ah LiFePO4 battery. Instead of putting the battery on the mower, I carried it in a backpack, which made the mower easier to maneuver. One thing that surprised me was how much current the motor used just spinning the blade in free air, not even cutting. It was 6-8 amps, if I'm not mistaken. Seems like a lot, doesn't it?
