DPV - Diver Propulsion Vehicle

The DPV features a magnetic coupling to transfer power from the motor to the propeller, eliminating the dynamic shaft seal. It uses the common Oceanic/Mako propeller and shroud since these are readily avaliable at an acceptable price. For propulsion I  used a 500W 48VDC brushless DC motor from Goldenmotor (BLT-500), powered by a 10Ah LiFePO4 battery package I built myself.
