Freefly Alta X 12S Flight Battery: 16Ah LiPo Power With XT90S Connector

The Freefly Alta X 12S Flight Battery delivers the power a heavy-lift platform demands, packing 16Ah at 44.4V into a LiPo pack built specifically for the original Alta X. This is not the standard battery for the Alta X Gen2, which uses a separate smart battery with an AS150U connector. An XT90S connector makes field connections fast and secure, and since each Alta X flight requires two batteries working together, this listing covers a single unit ready to pair with an existing battery or a matching second purchase.

Operators running an updated Alta X setup will find this newer generation pack has the balance lead clip removed, a design change worth noting if older leads are still in rotation. Rated for 15C continuous discharge and up to 30C burst, this battery is built to keep pace with demanding lift and payload requirements across a full flight schedule.

Key Features and Benefits

  • High capacity: delivers 16Ah at 44.4V per battery unit
  • XT90S connector: enables fast, secure field connections
  • Strong discharge rating: supports 15C continuous and 30C burst
  • Updated design: removes balance lead clip for streamlined connections
  • Paired operation: two batteries power one Alta X flight together

A heavy-lift aircraft is only as reliable as the power behind it, and this battery is rated to match the Alta X's demanding output requirements. Consistent discharge performance across a full flight schedule keeps missions on track without unexpected power limitations.

Dronefly stocks the flight batteries that keep Alta X platforms mission ready, whether you're powering a single aircraft or building out a broader battery rotation.

How many batteries do I need for one Alta X flight?

The Alta X requires two 12S batteries working together per flight, and this listing is for a single battery unit. Order two to have a complete flight-ready pair on hand. Actual flight time depends on payload weight and flight conditions.

Is this battery compatible with my current charging leads?

This is a newer generation flight pack with the balance lead clip feature removed. If your existing leads include that clip, it will need to be removed from the lead connector for a proper fit. A compatible XT90-capable 12S LiPo charger is sold separately.

Does this battery work with the Alta X Gen2?

No, this battery is built for the original Alta X. The Alta X Gen2 requires a separate smart battery with an AS150U connector, which adds features like a fuel gauge and current detection that communicate directly with the aircraft. Confirm which Alta X platform you're flying with Dronefly before ordering to get the correct battery.

What discharge rate does this battery support?

This battery is rated for a maximum continuous discharge of 15C and a maximum burst discharge of 30C, supporting the output needs of heavy-lift flight. Maximum charge voltage is 4.2V per cell, with a minimum discharge voltage of 3.0V per cell.
