Can BestBoatWire install lugs on battery cables ? Unfortunately, we do not install any battery lugs. We stopped this practice because of liability issues and past frivolous lawsuits. You can do it yourself using battery crimper found in our Tools category, however, they are not cheap. Another option would be to use your local marine electrician for this task or visit your tool rental shop. As a last resort, a car/truck repair facility might have the required size crimper.
