The FBC11071170PS3 6S1P is the highest-capacity single-string 6S soft pack battery in the ampKRAFT PS3 Series. Built on the 170mm cell format, it delivers a nominal capacity of 21,200mAh (typical 22,000mAh) at 21.6V nominal voltage, resulting in 475Wh of usable energy per charge cycle at a weight of 1,752g.
Despite the high capacity, the pack maintains a slim 71mm thickness, only 5.5mm more than the 20000mAh variant, while delivering an additional 43Wh of energy. The continuous discharge of 130A and burst of 180A match the performance of the 20000mAh variant, making this pack a straightforward capacity upgrade for platforms already designed around the 170mm PS3 cell footprint.
At 1,752g and 475Wh, this 21.6V drone battery offers the best energy density in the 6S1P PS3 range, with an energy-to-weight ratio that makes it the preferred choice for mission profiles where maximum flight time is the primary objective. The QS8-S discharge connector and JST-XHP-7P balance connector are compatible with standard professional UAV integration setups.
For development teams who need more capacity than 475Wh at 21.6V, the FBC7871125PS3 6S2P in a parallel configuration delivers the same voltage at 21,200mAh nominal with higher continuous current capability, as an alternative pack architecture for the same voltage platform.
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 FBC11071170PS3 6S1P is a 6S1P soft pack drone battery with a nominal capacity of 21,200mAh and a typical capacity of 22,000mAh. The nominal voltage is 21.6V based on a 3.6V per cell configuration. The pack delivers 475Wh of usable energy and weighs 1,752g. Physical dimensions are 180mm length, 74mm width, and 71mm thickness, with a QS8-S discharge connector and JST-XHP-7P balance connector. It is the highest-capacity single-string 6S pack in the ampKRAFT PS3 Series.
Both packs use the 170mm PS3 cell format and share the same 21.6V nominal voltage, 74mm width, and 180mm length. The 22000mAh variant adds 150g and 5.5mm of thickness compared to the 20000mAh pack, while delivering an additional 43Wh of energy. Discharge performance is identical at 130A continuous and 180A burst. For platforms where the airframe can accommodate the additional 5.5mm of pack thickness, the 22000mAh variant is the direct endurance upgrade with no changes required to the electrical integration.
The FBC11071170PS3 6S1P supports a continuous discharge of 130A over 60 seconds at 25°C and a burst of 180A for up to 10 seconds. Continuous discharge power is 2,808W and burst discharge power reaches 3,888W. The AC impedance of ≤19 mΩ is consistent across the 170mm PS3 cell format, contributing to a stable and flat voltage curve under sustained high-current demand throughout the full discharge cycle.
The FBC11071170PS3 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.
