For my job I have Hilti Nuron tools. Currently I own 4 batteries. I have 2 of these mounts connected to a piece of board. The 4 batteries can be clicked onto the mounts. The board with 2 mounts and 4 batteries can be carried around.
Added 2 pieces which ‘connect’ together (need screws and board) to hold 4 batteries closer together
