A system, an electrical combination and a method for powering a load device. The combination may include a burst circuit configured to provide power to the load device to perform a burst operation, the burst circuit including a supercapacitor, a first switch between a power source and the supercapacitor and operable to control whether power is provided from the power source to charge the supercapacitor, and a second switch between the supercapacitor and the load device and operable to control whether power is provided from the supercapacitor to the load device; and an electronic processor configured to control the first switch and the second switch based at least in part on a voltage of the supercapacitor.

An adapter for use with a battery compartment of an electronic device is provided. The adapter includes a first section adapted to receive a first portion of at least one first battery. The adapter also includes a second section disposed adjacent to the first section. The second section is adapted to receive a second portion of the at least one first battery. The adapter further includes an articulating joint disposed between the first section and the second section. The articulating joint is adapted to selectively articulate the first section relative to the second section to move the adapter between a first position and a second position. In the first position, the adapter is adapted to be aligned in the battery compartment. In the second position, the adapter is adapted to be removably secured in the battery compartment.

A battery pack includes a housing and electrochemical cells disposed in the housing. The housing includes a container and a lid that closes an open end of the container. The container has a base, an outer wall the surrounds the base, and a first and a second inner wall disposed inside the outer wall. The first inner wall extends between, and is fixed to, a first portion and a third portion of the outer wall, and is spaced apart from a second portion and a fourth portion of the outer wall. The second inner wall extends between the first portion and the third portion, and is disposed between the first inner wall and the fourth portion. The second inner wall is movable relative to the outer wall such that spacing of the second inner wall from the first inner wall can be changed.

The present disclosure is directed to a reversible battery tray that has a plurality of first boundary reception areas at a first side, and a plurality of second boundary reception areas at a second side opposite to the first side. The first boundary reception areas have a first shape to receive a first type of battery with a corresponding second shape, and the second boundary reception areas have a third shape to receive a second type of battery with a corresponding fourth shape. The reversible battery tray may be positioned within a battery box such that the first side is exposed or the second side is exposed as selected by a user or an operator of a vehicle to utilize different types of batteries while also restraining movement of the selected type of battery by the user or the operator as well.
