Abstract
A battery pack, charger, and terminal blocks for the pack, charger and a cordless power tool are provided. The pack includes battery cells disposed between end caps within a bottom housing of the pack, and a potting boat for housing pack electronics electrically connected to the cells between the end caps and disposed within a pack top housing. A pack terminal block is connected to the potting boat within the top housing. The charger and the power tool each include a terminal block for providing electrical connections between the charger/tool and the battery pack. The terminal block is configured to float side-to-side to provide displaceable movement of the terminal block within the charger housing or tool housing for aligning the battery pack terminal block therein.
