ABOUT THIS CELL

The FBC10671125PS3 is a mid-range high-discharge LiPo pouch cell from the ampKRAFT PS3 Series, built in the 125mm cell format. With a nominal capacity of 14,400mAh (typical 15,000mAh) and a nominal voltage of 3.6V, it delivers strong energy density at a cell weight of 187g.

The continuous discharge capability of 225A (15C) and a 10-second burst of 300A (20C) place this cell firmly in the mid-range of the 125mm PS3 format. Compared to the smaller 11,000mAh variant, the FBC10671125PS3 adds 36% more capacity and significantly higher absolute current output, while staying within the same 124.5mm length and 70.5mm width. The additional 2.8mm of thickness (10.2mm vs. 7.4mm) accommodates the higher capacity without changing the cell footprint.

For pack designers working on 6S or 8S UAV battery assemblies, this cell provides a practical mid-point between the compact 11,000mAh entry-level cell and the larger 170mm format options. The consistent 70.5mm width across the full PS3 range simplifies pack architecture and tooling across multiple capacity tiers.

At 187g per cell, a 6S1P pack based on the FBC10671125PS3 would weigh approximately 1,122g in cells alone, delivering 15,000mAh at 21.6V nominal. This makes it well suited for mid-range UAV platforms where endurance and discharge capability need to be balanced against total system weight.

WHY AMPKRAFT 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.

What are the key specifications of the FBC10671125PS3?
The FBC10671125PS3 is a high-discharge LiPo pouch cell with a typical capacity of 15,000mAh and a nominal capacity of 14,400mAh. The nominal voltage is 3.6V. The cell delivers 225A continuous discharge at 15C and a 10-second burst of 300A at 20C. Physical dimensions are 124.5mm length, 70.5mm width, and 10.2mm thickness. Approx. weight is 187g. It is built on ampKRAFT’s PS3 soft pack cell technology within the 125mm format series.
The 125mm PS3 range includes cells from 11,000mAh to 16,700mAh, all sharing the same 124.5mm length and 70.5mm width. The FBC10671125PS3 at 15,000mAh sits in the mid-range, offering 36% more capacity than the 11,000mAh variant while adding only 51g and 2.8mm of thickness. Compared to the 16,700mAh top-of-range cell, it is 19g lighter and 1mm thinner, with a slightly lower continuous discharge current (225A vs. 250.5A). For pack designs where the additional current headroom of the 16,700mAh cell is not required, the FBC10671125PS3 provides a more weight-efficient option.
The FBC10671125PS3 supports a continuous discharge of 225A (15C) over 60 seconds at 25°C and a burst of 300A (20C) for up to 10 seconds. The nominal discharge current is 1C at 15.0A. Cut-off voltage is 2.5V. In a 6S1P configuration, this translates to a continuous discharge power of approximately 4,860W and burst power of approximately 6,480W at nominal pack voltage.
The FBC10671125PS3 uses tabs with a thickness of 0.3mm ±0.02mm, with widths of 25.0mm (negative) and 35.0mm (positive). Tab dimensions directly affect contact resistance and thermal performance at the cell-to-busbar interface. Thicker or wider tabs reduce resistance and improve heat dissipation during high-current discharge. For pack assemblers using spot welding or ultrasonic bonding, consistent tab thickness across cells ensures uniform joint quality and repeatable assembly processes.
