I don’t find mine has any effect on the battery of my wahoo roam or my garmin 130From my experience and of course its very dependent on the amount of traffic that you encounter on the audax, but be very mindful of the drain on your GPS battery. I would be very surprised if running the light/radar plus running navigation on the GPS your battery lasts the duration of the audax to be honest?
I think if you’ve a older battery it must effect it more
try fitting a new battery to you 500
I can do a 100 ml ride using my roam with di2 ,power meter ,hr monitor and radar and it will only use about 30%
