GNB 3000mAh 2S goggle battery is simply better and more convenient compared to any other option.

-Bigger capacity than most other goggle batteries to spend your time flying and not charging!
-We asked GNB to use XT60 charging connector to keep it as compact as possible yet easy to charge just like your flight packs with your conventional lipo charger.
-Percentage checker so there are no surprises and annoying beeping from your goggles when you’re in the final lap leading that race.
-High quality barrel connector with “spring loaded” side pins

Note:

Don’t get too excited now 🙂

The “ON/OFF” button is ONLY for checking the percentage of the battery, it is NOT a power button.
