I’m getting ready to put my turbo Tero on the bike rack but it’s heavy enough that I want to remove the battery. The problem is, the battery compartment is then exposed to the elements and I don’t want water to spray up from the car onto the terminals and into the frame. Does anyone have a good idea of how to cover the battery hole while it’s on the car rack? I thought about tape and plastic bags but I’d like something that’s easier to put on
