Abstract: A chainsaw includes a body housing, an elongated guide bar projecting forward from the body housing, a saw-chain mounted on the periphery of the guide bar for rotation, an electric motor mounted within the body housing for rotating, and a top handle provided on an upper portion of the body housing above the guide bar and extending in a fore-and-aft direction. A plurality of rechargeable battery packs is mounted on the body housing as a source of power supply for the electric motor. The battery packs are mounted to the body housing in such a manner that a center of gravity of the chainsaw observed from the back side is positioned in a two times extent of lateral width of a gripe portion of the top handle at both sides of a vertical centerline of the gripe portion.
