Function: There are many specifications and models. The protective support of the lead end of the battery pack is used to improve the stability of the protective support, and then improve the connection effect between the conductive row and the lead end.
Material: insulating plastic, each bracket is embedded in two nuts, model m5.
Black model does not distinguish between positive and negative electrodes.
Red and black distinguish the positive and negative electrodes, the end plate opening at the right end is the positive electrode sheet, red represents the positive electrode; the end plate opening at the left end is the negative electrode sheet, black represents the negative electrode.
