High-voltage soft pack for direct UAV integration. 130A continuous discharge at 28.8V nominal, engineered for platforms that require higher voltage architecture without increasing cell count beyond eight series.
The FBC10171170PS3 8S1P is a high-voltage soft pack drone battery from the ampKRAFT PS3 Series. Built on the 170mm cell format in an 8S1P configuration, it delivers 20000mAh nominal capacity at 28.8V, resulting in 576Wh of usable energy per charge cycle. With a continuous discharge of 130A and a burst capability of 180A, it covers the power requirements of demanding UAV platforms where higher voltage reduces motor current and improves drivetrain efficiency.

The FBC10171170PS3 8S1P is a high-voltage soft pack drone battery from the ampKRAFT PS3 Series, built on the 170mm cell format in an 8-series configuration. With a nominal capacity of 19,200mAh (typical 20,000mAh) at 28.8V nominal voltage, it delivers 576Wh of usable energy per charge cycle at a pack weight of 2,096g.
The higher voltage architecture means the same 130A continuous discharge current translates to 3,744W of continuous discharge power, compared to 2,808W in the 6S equivalent. For UAV engineers, this means more power to the motors at lower current draw per ESC, reducing resistive losses and heat buildup in the drivetrain at sustained high power levels.
The 88mm thickness accommodates the additional series cell while maintaining the same 74mm width and 180mm length as the 6S1P variant, making it a drop-in voltage upgrade for airframes designed around the 170mm PS3 cell footprint. The QS8-S discharge connector and JST-XHP-9P balance connector are standard fittings for professional 8S UAV integration setups.
For development teams working across voltage platforms, the PS3 Series covers both 6S (21.6V) and 8S (28.8V) configurations within the same cell family, using identical width and length dimensions to simplify multi-platform pack design.
Sourcing a professional 8S 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 28.8V soft pack battery into an existing airframe or developing a new high-voltage UAV platform from scratch, ampKRAFT is the right partner to have early in the process.

The FBC10171170PS3 8S1P is an 8S1P soft pack drone battery with a nominal capacity of 19,200mAh and a typical capacity of 20,000mAh. The nominal voltage is 28.8V based on a 3.6V per cell configuration across eight series cells. The pack delivers 576Wh of usable energy and weighs 2,096g. Physical dimensions are 180mm length, 74mm width, and 88mm thickness, with a QS8-S discharge connector and JST-XHP-9P balance connector.
Higher voltage directly reduces the current required to deliver the same power to the motors. At 28.8V, the same 3,744W continuous discharge power requires 130A, identical to the 6S variant but with significantly more power output. Lower current per motor means less heat in the ESCs and wiring, more efficient power delivery, and better performance at sustained high throttle. For heavy-lift platforms or long-endurance missions where drivetrain efficiency matters, the 8S architecture is a meaningful improvement over 6S.
Both variants use the same PS3 170mm cell format and share the same 74mm width and 180mm length. The 8S1P adds two additional series cells, increasing the nominal voltage from 21.6V to 28.8V and the pack thickness from 65.5mm to 88mm. Capacity remains the same at 19,200mAh nominal. The charge cut-off voltage increases from 25.2V to 33.6V, requiring an 8S-capable charger. The balance connector changes from JST-XHP-7P to JST-XHP-9P to accommodate the two additional cells.
The FBC10171170PS3 8S1P 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.
