All batteries are not created equal or at least not all lenses are created equal. I carry a spare battery, as does my group. You can turn them on at the truck and run them all day with 2. I typically turn mine off when stopped for a break etc, so I can usually make an entire day on a battery, 3-4 hours of riding.So for those of you that have the ignite goggles, do you carry an extra battery or is one battery enough for a typical days ride?
If you go to Yamaheater.com and look under “Products “ he has a plug and play kit that runs off heated shield outlet . No more Battery for the 509 .
