Abstract: An implementation of a battery cradle includes a tray, a first side frame attached to a first side of the tray, and a second side frame attached to a second side of the frame. The first side frame and the second side frame face each other and are substantially parallel to one another. Both the first side frame and the second side frame include a plurality of generally circular recesses, in which each recess on the first side frame is opposite to and aligned with a recess on the second side frame. Each pair of aligned recesses accommodates a generally cylindrical battery. According to various implementations, the tray includes (i) a plurality of depressions, each of which is aligned with a pair of aligned recesses and (ii) a plurality of slats configured to accommodate a prism-shaped battery pack.

Abstract: Disclosed herein is a multi-axle component for a constant-velocity drive type driveshaft joint system, comprising: a rotation shaft comprising an end distal to a joint region, and an end proximate to the joint region; a generally cylindrical ball receiving housing located at the proximate end, comprising a cylindrical wall adapted to receive at least a partially spherically shaped shaft end; at least two holes provided in the cylindrical wall that are axially displaced from one another along a rotation axis of the multi-axle component; and a pin that extends through only one of the axially displaced holes at a time to join the shaft end with the multi-axle component.
