Looks like it can be affected affected by temperature. I don't ride in 131 degree's, but I could see riding in 14F or less sometimes (as long as the roads are clear and I have my heated gear on)

Operating Temperature: -10˚C – 55˚C (14°F – 131°F)

When you connect this thing to the intercom cable on the bike; does that cable also recharge it as you are using it? Does the interconnecting cable have that ability?
