Solder Slugs

These contain solder & flux and replace having to crimp battery connectors. Simply strip the cable, slide a piece of heatshrink tubing onto the cable, drop the slug into the connector and melt it with a torch, push the cable in, slide the heatshrink tubing over the connection, and melt with a torch. This creates a waterproof connection with unmatched connectiving and resistance to pull-out.
