Reviving ViFly Finder Batteries After Deep Discharge Issues

Hey everyone!

I'm sure some of you also use the ViFly Finder for your copters to locate them if you unexpectedly crash them somewhere. Have you ever experienced them seemingly being broken in winter or after a long period of disuse? Deep discharge or a defective battery? I've discovered that in many cases, you can revive them by directly connecting the battery to a 1S (3.7V) charger for about 8 to 10 seconds. The reason is indeed deep discharge, where the threshold can only be overcome with a more aggressive method. Normal charging won't help.

Maybe this will help someone.

Happy flying!
