funny enough, I put that bracket on backwards and I didn't hear any rattling at all today and part of the road to work is rough enough that I would have heard some.
Oops lol. It is working out fine though. Usually my 7 mile ride in this cold weather would knock out 1 sometimes 2 bars on the battery depending on how much pas I use but today I haven't even knocked off 1 bar yet.
Add on battery came today. Installation was easy if you follow the video but the middle bolt for the bracket was too short so I had to make a trip to the hardware store.
I would be interested in this video. I plan on getting the extender battery and maybe even a third party cuttle battery and just keep it in my bag and swap it when needed.
