Compare the six connector shapes shown in the product images and verify the 23 mm cell spacing, polarity, terminal positions, PCB/BMS connections, and housing clearance against your exact case before welding. Modification may be required if your case layout differs. The matching M18 FORGE 8Ah-style 21700 battery case is sold separately. Select the 21700 / 8Ah FORGE-style option, not the 18650 / 6Ah option. Installation and Safety Test-fit all six connectors before making any welds. Confirm cell orientation, polarity, and every series connection. Use fish-paper rings and suitable electrical insulation throughout the pack. Use welding equipment and settings appropriate for copper-nickel composite material. Do not exceed the safe limits of the cells, PCB/BMS, terminals, welds, wiring, or complete battery assembly.
