6 plus spare battery

[Mori55]

I ordered a spare battery to take with at times.
  I have the front basket and rear rack with small basket. The battery is to long to fit in these and looks like crap hanging out.
  I also have the travel case for the battery.
Any idea on how to carry this without taking the rear basket off and strapping to the rack ?

Me too. I got 2 extra batteries for my wife and I and haven't figured it out yet. However, I'm thinking I'm going to use the carrying case and secure it on the underside of the down tube. I'm taking pictures to my local Ace hardware store so they can help me figure out that right clamps, ties and/or straps. Theoretically this space on the bike should work. I'll let you know and send pics.
