It's the second best way to charge a battery externally. You can also find one connected to the batterycase. So also If you get an extra battery case for the NLS Pro or Mini 2 you can charge the backup battery with the battery level being displayed. But if you don't want a lunky case and just want to use the perfectly fine red and green indicators on the chargers it works just as well.
Battery came really fast . About to weeks... I was really surprised... Didn't know what the adapter was for but now I know, it's for out of board charging... Wonderful
Nice that you can charge extra battery and go out and drive the board at the same time haha then you could drive all day haha thanks best meepo. Meepo for live
