I recently just got a hill topper from Clean Republic. I've been mounting it on a front rack. I am nervous to ever leave the battery on the bike, so I've been disconnecting it and taking it with me, but this is a huge pain, as well as I then have to lug a 4.5lb battery around. I'm looking for some sort of basket or bag that I can put it in, and leave it in locked up when I go somewhere. I've been trying to find like a wire basket with a lid, but I have not found one! I'm interested in locking it on the front or back rack. Any suggestions? Thanks.
My battery slides into the rear rack that came with it, then it locks with a key, but the rack is still held on by only a few screws and could be removed fairly quickly. Even if I could lock the rack to the bike, I wouldn't leave the battery on the bike unless I was willing to replace it. That's a $375 part waiting to be stolen.
