Highest-capacity cell in the PS3 Series. 330A continuous discharge and 21,200mAh nominal in the 170mm format, designed for high-current pack architectures where maximum energy per cell is the primary objective.
The FBC11071170PS3 is the highest-capacity cell in the ampKRAFT PS3 Series. At 21,200mAh nominal (typical 22,000mAh) and 272g, it delivers the maximum energy per cell available in the PS3 range within the 170mm format. With a continuous discharge of 330A at 15C and burst capability of 440A at 20C, it is the cell of choice for pack architectures that require both maximum capacity and the highest sustained current output in the PS3 family.

The FBC11071170PS3 is the highest-capacity and highest-current cell in the ampKRAFT PS3 Series. At 21,200mAh nominal and 272g, it delivers the maximum energy per cell available across the full PS3 range. The 330A continuous discharge at 15C and 440A burst at 20C make it the strongest performer in the 170mm format, exceeding the FBC10171170PS3 by 30A continuous and 40A burst while adding only 25g and 0.9mm of thickness.
For engineers building 6S1P packs at 21.6V, a single string of six FBC11071170PS3 cells delivers 475Wh nominal, the highest energy available in a 6S1P PS3 configuration. In an 8S1P configuration at 28.8V, the same cell delivers 634Wh per pack, making it the cell behind the highest-energy pack in the full PS3 soft pack range.
The low AC impedance of ≤2.5 mΩ, consistent with the FBC10171170PS3, ensures stable voltage output under the high continuous current draw that characterises demanding UAV mission profiles. The shared tab dimensions and thickness of 0.3mm across both 170mm cells simplifies welding process setup when both cells are used within the same production line.
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 FBC11071170PS3 pouch cell. If your question is not covered here, our engineering team is happy to help directly.
The FBC11071170PS3 combines the highest nominal capacity in the PS3 range at 21,200mAh with the highest continuous discharge current at 330A and the highest burst current at 440A. No other cell in the PS3 Series delivers this combination within a single cell. In 6S1P configuration it produces 475Wh, and in 8S1P it delivers 634Wh, both the maximum values available in the PS3 soft pack range. For engineers optimising for maximum energy and current output per cell, this is the cell that defines the top end of the PS3 family.
Both cells share the same 170mm format, 70.5mm width, 3.6V nominal voltage, and ≤2.5 mΩ AC impedance. The FBC11071170PS3 adds 2,000mAh nominal capacity, 30A continuous discharge current, and 40A burst current compared to the FBC10171170PS3, at the cost of 25g additional weight and 0.9mm additional thickness. For pack designs where the available depth accommodates the extra 0.9mm, this cell is the direct performance upgrade with no changes required to the pack voltage architecture or charging setup.
The FBC11071170PS3 is most commonly used in 6S1P configurations at 21.6V nominal, delivering 475Wh per pack, and in 8S1P configurations at 28.8V nominal, delivering 634Wh per pack. These are the configurations covered by the finished soft pack variants FBC11071170PS3 6S1P and FBC11071170PS3 8S1P. Custom configurations including higher series counts or parallel arrangements are supported on request through our engineering team.
The FBC11071170PS3 is rated for discharge between -20°C and +60°C. Charging should take place between 0°C and +45°C with temperature-dependent charge rates from 0.2C at low temperatures up to 1C between 20°C and 35°C. Storage limits are -20°C to +45°C for up to one month and -20°C to +30°C for longer periods. Cell surface temperature limits are 0°C to +55°C for charging and -20°C to +85°C for discharge under limit conditions.
