Freefly Alta X 12S Flight Pack – 16 Ah 15C (Single Battery) is the purpose-fit power source for Alta X operations. Each flight uses two packs in parallel; purchase as singles to scale your kit. The pack connects via XT90S and is compatible with XT90-capable 12S LiPo chargers for rapid turnaround.

This generation removes the balance-lead clip. If your balance leads have a clip installed, remove it from the connector so it mates correctly with the charger harness. Flight time depends on payload and conditions; refer to the Alta X Flight Manual for mission-specific estimates.
