The invention belongs to the technical field of battery modules, particularly relates to a method for reducing internal resistance of a module, and aims to solve the problems that the internal resistance of the existing module is relatively large and the use of the module is influenced, the method comprises the following steps: S1, manufacturing a parallel battery pack which comprises parallel battery cells, a positive electrode parallel sheet, a negative electrode parallel sheet and an insulating bag, the multiple parallel cells are wrapped in the insulating bag, the positive electrode parallel sheet is connected with the positive electrodes of the multiple parallel cells, the negative electrode parallel sheet is connected with the negative electrodes of the multiple parallel cells, and in the series connection process of the interior of the Pack module, although currents flowing through a series connection circuit are the same in magnitude, the different series connection modes can cause different current f
