As shown in fig. 1 to 3, in an embodiment, the present invention provides an adjustable battery pack connecting sheet, which can connect batteries 300 with different specifications to form a battery pack, and mainly includes a conductive connecting sheet 100 and an electrode fixing sheet 200 movably mounted on the conductive connecting sheet 100, wherein the electrode fixing sheet 200 can slide along the conductive connecting sheet 100; the surface of the electrode fixing piece 200 is provided with an electrode fixing cap 210 protruding outwards, and the bottom wall of the electrode fixing cap 210 is provided with a plurality of first conductive contacts; the electrode fixing sheet 200 is used to fix the electrode of the battery 300 and electrically connected to the electrode, that is, the electrode of the battery 300 is fixed to the motor fixing cap, and the battery 300 is fixed by welding the first conductive contact to the electrode fixing cap 210. The conductive tab 100 is stamped with a fixing cap mounting groove 110 arranged along the extending direction of the conductive tab 100, the conductive tab 100 is attached to the electrode fixing tab 200 and the electrode fixing cap 210 is slidably inserted into the fixing cap mounting groove 110. Because the electrode fixing cap 210 of the electrode fixing plate 200 is in sliding fit with the fixing cap mounting groove 110 of the conductive connecting piece 100, the electrode fixing plate 200 can slide on the conductive connecting piece 100, the distance between two adjacent electrode fixing plates 200 can be adjusted as required to adapt to the assembly of battery packs of different specifications, the electrode fixing plate 200 and the conductive connecting piece 100 are fixed in a spot welding manner after the position is determined, and the conductive connection and mounting of the battery packs are realized.
