BATTERY PACK AND ELECTRICAL COMBINATION

摘要

An electrical combination with a battery pack and a power tool. The battery pack includes two battery pack connectors which are connected with the same electrode of a battery of the battery pack. A circuit of one battery pack connector has a resistance greater than that in another circuit of another battery pack connector. The power tool includes corresponding tool connectors. When the battery pack is connected with the power tool, the power tool is supplied with a small current by the battery pack firstly, and then is supplied with a large current, so an electric spark is eliminated when the terminals of the battery pack contact with the terminals of the power tool. 20:1, l 2)(1 21k. m~we~ dric
