The FBC10671125PS3 6S1P is a mid-range soft pack drone battery from the ampKRAFT PS3 Series, built on the 125mm cell format. With a nominal capacity of 14,400mAh (typical 15,000mAh) and a nominal voltage of 21.6V, it delivers 324Wh of usable energy at a pack weight of 1,232g.
The high-discharge design supports a continuous draw of 120A over 60 seconds and a burst of 180A for up to 10 seconds, with continuous discharge power reaching 2,592W. The 68.5mm thickness positions this pack between the compact 11000mAh variant and the larger 170mm format cells, covering platforms that need a meaningful capacity increase over the entry-level pack without moving to the larger cell footprint.
At 1,232g and 324Wh, this 21.6V drone battery delivers a strong energy-to-weight ratio for light to medium-payload platforms where endurance is a priority but airframe weight limits rule out the heavier 170mm format packs. The QS8-S discharge connector and JST-XHP-7P balance connector are compatible with standard professional UAV integration setups.
For development teams working across the PS3 Series, the 125mm cell format covers capacities from 10,600mAh to 16,000mAh nominal at the same 21.6V voltage and 74mm width, making it straightforward to select the right capacity for each platform without changing the integration architecture.
Sourcing a professional 6S drone battery means more than matching a voltage and capacity spec. Flight-critical applications demand consistent cell quality, verified discharge performance, and a supplier who understands the difference between a datasheet and a flying platform.
ampKRAFT’s PS3 Series soft pack batteries are manufactured under a fully vertically integrated production process, with proprietary intellectual property covering cell chemistry, materials, and quality control. Every batch is traceable, and every cell is built to the same specification as the one before it.
For UAV engineers and procurement teams working on professional drone platforms, inspection systems, or defense-adjacent applications, ampKRAFT provides direct access to the source technology, not a rebranded off-the-shelf product. Custom configurations, alternative connectors, and volume pricing are available on request, supported by a dedicated engineering team with hands-on UAV application experience.
Whether you are integrating a 21.6V soft pack battery into an existing airframe or developing a new UAV platform from scratch, ampKRAFT is the right partner to have early in the process.

The FBC10671125PS3 6S1P is a 6S1P soft pack drone battery with a nominal capacity of 14,400mAh and a typical capacity of 15,000mAh. The nominal voltage is 21.6V based on a 3.6V per cell configuration. The pack delivers 324Wh of usable energy and weighs 1,232g. Physical dimensions are 135.5mm length, 74mm width, and 68.5mm thickness, with a QS8-S discharge connector and JST-XHP-7P balance connector. It is built on the 125mm PS3 cell format with full traceability across production batches.
All three packs share the same 21.6V nominal voltage and 74mm cell width. The 11000mAh variant is the lightest at 880g and 51.5mm thickness, best suited for compact and weight-sensitive platforms. The 15000mAh pack adds 352g and 17mm of thickness for a 36% capacity increase, making it a practical mid-step for platforms that need more endurance without moving to the larger 170mm cell format. The 20000mAh pack uses the 170mm cell format and is heavier at 1,602g but delivers 432Wh, suited for platforms specifically designed for the longer cell dimensions.
The FBC10671125PS3 6S1P supports a continuous discharge of 120A over 60 seconds at 25°C and a burst of 180A for up to 10 seconds. Continuous discharge power is 2,592W and burst discharge power reaches 3,888W. The AC impedance of ≤19 mΩ is consistent with the other 125mm format PS3 cells, contributing to stable voltage output under sustained high-current demand.
The FBC10671125PS3 6S1P is rated for discharge between -20°C and +60°C, covering the full range of standard professional field conditions. 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.
