I'm adding a second battery. The isolator has two mounting holes. Each less than 1/8" diameter. Tiny. Don't want to drill them out because the unit is sealed against moisture. Mounting it behind seat on angled back on my XP1000. Thinking just use a silicone adhesive to mount it. I also am adding a waterproof 100 amp breaker. Any reason why I can't use a silicone adhesive to mount them?
