I've found that in the cold winter weather I'm only getting 25-30 km range out of my Challenger. So I'm thinking of carrying a spare battery to double the range. Has anyone done that?

My current plan is to carry the spare battery on the footplate above the first one, held on with numerous bungee.

I see Veloteq is coming out with a new and improved battery. Anyone heard anything about when it comes out? I may hold off buying a second battery until a better one comes out if that will be anytime soon.
