My oil tank on the shovel is mounted with them. I like the idea behind it, but a broken one resulted in an oil tank that hung down, stopped me from shifting and connected to positive terminal with the frame. This melted the negative and made the oil tank about 300 degrees. Luckily I run a mag and I was close to home. I had to miss the liberty party and get the bike home, but by disconnecting the battery, I wouldn't burn alive from lava oil and my bike runs fine with the mag only. Now it's time for one of those little Ballistic batteries.
