Don't be surprised if you never have to charge your XC Tracer Mini V during a whole season! The vario has a built-in lithium-polymer battery which, fully charged, lasts for about 30 hours of continuous use. But as the battery is recharged during flight by the built-in solar cells, the autonomy is almost unlimited. Thanks to the instantaneous climb/descent display, finding and centring thermals is much easier with a Mini V than with a conventional variometer.
