BP185 Solder slugs, for 4-gauge battery cable lugs

These Standard solder slugs are pre-measured pellets designed specifically for 4-gauge battery cable lugs. To use, simply insert a slug into the lug, heat it with a torch while held in a vice, and press the battery cable into the molten solder for a permanent, low-resistance connection. This method provides a superior electrical bond compared to crimping alone, ensuring maximum cranking power for your Harley-Davidson. It is recommended to use heat shrink tubing to create a weatherproof seal after the soldering process is complete. These solder slugs are sold in packs of 10.
