For sale Matrice 210 V2 dual gimbal, with 12 batteries, 2 controller batteries, stock chargers and simultaneous chargers, Cendence controller and Crystal Sky monitor. Asking $13,500.00 for the complete set.
Flight miles are a mis-nomer and not truly tracked. Individual pilot logs via DJI Apps, perhaps.... but as "professionals", we know that multiple users could have used a single UAV. Battery Cycle counts are a trackable entity, but that could vary considerably too... as I often charge many of my TB55s after their trickle discharge without a flight.
Discussion with the seller is the only 'true' gauge of usage.
