Compact high-discharge LiPo pouch cell for professional UAV battery pack assembly. 15C continuous and 20C burst in the slimmest profile of the PS3 125mm format at 7.4mm thickness.
The FBC7871125PS3 is the entry-level cell in the ampKRAFT PS3 125mm Series and the slimmest cell in the entire PS3 range at 7.4mm thickness. With a nominal capacity of 10,600mAh (typical 11,000mAh) and a continuous discharge capability of 165A at 15C, it is well suited for compact pack designs where form factor and weight are the primary constraints. At 136g, it is the lightest PS3 cell available and shares the same 70.5mm width as the full PS3 range for consistent pack assembly tooling.

The FBC7871125PS3 is the entry-level cell in the ampKRAFT PS3 125mm Series and the slimmest cell across the entire PS3 range. At 7.4mm thickness and 136g, it is designed for pack architectures where minimizing thickness and weight per cell is the primary objective, without sacrificing the 15C continuous discharge capability that defines the PS3 Series.
The continuous discharge of 165A at 15C and burst of 220A at 20C cover the current requirements of compact UAV platforms in the light to mid-payload range. The AC impedance of ≤3.0 mΩ is slightly higher than the larger PS3 cells, which reflects the thinner electrode stack, but remains well within the range required for stable voltage output in professional UAV applications.
For pack designers working across the PS3 125mm format, this cell is the natural starting point for weight-optimized 6S1P designs. The 6S2P configuration using two parallel strings of this cell delivers 21,200mAh nominal at the same 21.6V voltage, doubling capacity and increasing continuous current to 330A within a pack that remains shorter than the 170mm format cells.
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.
Everything you need to know about the FBC7871125PS3 pouch cell. If your question is not covered here, our engineering team is happy to help directly.
The FBC7871125PS3 is the slimmest cell in the PS3 range at 7.4mm thickness and the lightest at 136g. For airframe designs where the available pack bay depth is limited, this cell allows a 6S1P pack to achieve a significantly lower profile than any other PS3 cell. At 10,600mAh nominal, it covers the capacity requirements of light-payload UAVs and compact inspection platforms where endurance is secondary to form factor and agility.
The PS3 125mm Series covers three capacity tiers: this cell at 10,600mAh nominal (136g, 7.4mm), the FBC10671125PS3 at 14,400mAh nominal (187g, 10.2mm), and the FBC11671125PS3 at 16,000mAh nominal (206g, 11.2mm). The FBC7871125PS3 has a slightly higher AC impedance of ≤3.0 mΩ compared to ≤2.5 mΩ for the larger cells, which reflects the thinner electrode stack. For applications where the 165A continuous current capability is sufficient and minimizing pack thickness is the priority, this cell is the right choice.
Yes. Two parallel strings of FBC7871125PS3 cells in a 6S2P configuration deliver 21,200mAh nominal at 21.6V nominal, with a combined continuous discharge current of 330A. The 6S2P pack using this cell is available as a finished soft pack (FBC7871125PS3 6S2P) with QS8-S connector and yellow PVC sleeve. If you need a custom 6S2P configuration with different connectors or modified dimensions, our engineering team can support the design.
The tab thickness of the FBC7871125PS3 is 0.2 ±0.02mm, compared to 0.3 ±0.02mm for the larger PS3 cells. This is relevant for welding process parameters during pack assembly. Thinner tabs require adjusted laser or ultrasonic welding settings to achieve reliable connections without damaging the electrode foil. Our engineering team can provide process guidance for assemblers setting up production lines using PS3 cells.
Yes. ampKRAFT supplies PS3 cells for OEM pack assembly programs, custom battery development projects, and turnkey production line customers. Because we own the manufacturing IP and process, we can support volume supply with consistent batch specifications and full production traceability. To discuss volume pricing, lead times, or custom cell requirements, submit a technical request and our team will respond within one business day.
