A rechargeable lithium battery electric tool comprises a holder portion (1), a gearbox (2), a motor (3), a handle (9) and a battery pack (6). The battery pack is arranged inside the handle and comprises 4 lithium batteries, a battery shell and a battery base, the four lithium batteries are installed inside the battery shell whose bottom is provided with a battery base (8), and the battery base is connected to the handle through insertion. The present invention combines the advantages of a compact rechargeable lithium battery electric tool and a high-power output rechargeable lithium battery electric tool, the rechargeable lithium battery electric tool of the present invention, on one hand, meets the power demand of high power output by adopting a 14.4V to 16V lithium battery system as the power basis and platform, and on the other hand, reduces the overall volume of the machine body of the electric tool because the battery pack containing 4 lithium batteries is designed inside the handle. At the same time, the power of the tool is enhanced while the overall volume of the machine body is reduced due to the use of mini rare earth motor.
