High-discharge LiPo pouch cell for professional UAV battery pack assembly. 15C continuous and 20C burst within the compact 125mm cell format.
The FBC11671125PS3 is a high-discharge LiPo pouch cell from the ampKRAFT PS3 Series, built in the 125mm cell format. With a nominal capacity of 16,000mAh (typical 16,700mAh) and a continuous discharge capability of 250.5A at 15C, it is the highest-current cell in the 125mm PS3 format. Designed for professional UAV battery pack assembly, it shares the same 70.5mm cell width as the full PS3 range, ensuring consistent integration across 125mm and 170mm format pack designs.

The FBC11671125PS3 is the highest-capacity cell in the ampKRAFT PS3 125mm Series. At 16,000mAh nominal and 206g, it delivers the strongest energy-to-weight ratio within the 125mm format, making it the preferred cell for pack designs that are constrained to the 124.5mm cell length but need maximum capacity per cell.
The continuous discharge capability of 250.5A at 15C and burst capability of 334A at 20C make this cell well suited for high-current pack architectures. The low AC impedance of ≤2.5 mΩ contributes to a stable voltage curve under sustained high-current draw, which is critical for UAV platforms where voltage sag directly affects flight controller behaviour and motor performance.
All PS3 Series cells share the same 70.5mm width, which simplifies pack tooling and assembly across the 125mm and 170mm cell formats. For engineers building packs across multiple platform sizes, this dimensional consistency reduces design iterations and tooling costs when stepping between capacity tiers.
Sourcing cells for professional UAV battery pack assembly requires more than a datasheet match. Production consistency, batch traceability, and direct access to the cell manufacturer are the factors that determine whether a pack performs reliably in the field and whether supply can scale with your program.
ampKRAFT owns the intellectual property for the PS3 cell chemistry and manufacturing process. This means cells are not sourced from a third-party manufacturer and relabelled. Every production batch comes with full traceability, and cell specifications are controlled at the source. For OEM manufacturers and pack assemblers working on professional drone platforms, this provides a level of supply chain transparency that is difficult to achieve with commodity cell sourcing.
Custom capacity tiers, modified tab configurations, and volume supply are available on request. Our engineering team works directly with pack development teams from cell selection through to qualification testing.

The cell datasheet covers the individual pouch cell as a standalone component. The soft pack datasheet covers a finished battery pack assembled from multiple cells in a specific series and parallel configuration, including the pack housing, connectors, and wiring. The FBC11671125PS3 cell is the same cell used in the FBC11671125PS3 6S1P soft pack, but the soft pack datasheet specifies pack-level voltage, dimensions, connectors, and discharge parameters rather than individual cell characteristics. If you are sourcing cells for your own pack assembly, the cell datasheet is the relevant document.
The FBC11671125PS3 can be assembled into any series or parallel configuration that matches your platform’s voltage and capacity requirements. The most common UAV configurations using PS3 125mm cells are 6S1P (21.6V nominal) and 6S2P (21.6V, doubled capacity). For higher voltage platforms, 8S1P configurations (28.8V nominal) are also supported. Because all PS3 cells share the same 70.5mm width, mixed format designs using both 125mm and 170mm cells in the same mechanical assembly are also feasible.
The C-rating refers to the discharge current as a multiple of the cell’s nominal capacity. For the FBC11671125PS3 at 16,000mAh nominal, 15C equals 240A. The datasheet specifies 250.5A continuous, which reflects the tested capability at 15C based on typical capacity of 16,700mAh. This current level can be sustained for 60 seconds at 25°C under standard test conditions. For burst events, the cell handles 334A at 20C for up to the burst duration specified in the datasheet.
The PS3 125mm Series includes three cells: the FBC7871125PS3 at 10,600mAh nominal (136g), the FBC10671125PS3 at 14,400mAh nominal (187g), and this cell at 16,000mAh nominal (206g). The FBC11671125PS3 is the largest and heaviest in the 125mm format, offering the highest capacity per cell within the 124.5mm length constraint. All three cells share the same 70.5mm width and 3.6V nominal voltage, and all support 15C continuous and 20C burst discharge.
