A robotic vehicle includes a chassis supported on right and left driven tracks, right and left elongated flippers disposed on corresponding sides of the chassis, and a battery unit holder disposed on the chassis for removably receiving a battery unit weighing at least 50 lbs. The battery unit holder includes a guide for receiving and guiding the battery unit to a connected position and a connector mount having locating features and communication features. The locating features receive corresponding locating features of the battery unit, as the battery unit is moved to its connected position, to align the communication features of the connector mount with corresponding communication features of the battery unit. The communication features of the connector mount are movable in a plane transverse to the guide to aid alignment of the communication features for establishment of an electrical connection therebetween when the battery unit is in its connected position.
