The FBC11071170PS3 8S1P is the highest-energy pack in the ampKRAFT PS3 Series. Built on the 170mm cell format in an 8S1P configuration, it delivers a nominal capacity of 21,200mAh (typical 22,000mAh) at 28.8V nominal voltage, resulting in 634Wh of usable energy per charge cycle at a weight of 2,296g.
The 8S configuration increases the continuous discharge power to 3,744W and burst power to 5,184W compared to the 6S equivalent, while maintaining the same 130A and 180A current ratings. This means the same current delivers significantly more power to the motors, making the 8S architecture the preferred choice for heavy-lift platforms and high-power drive systems where current draw per ESC needs to stay within manageable limits.
At 94mm thickness, this pack is the deepest in the PS3 range, adding 23mm over the 6S1P variant at the same cell format. The same 74mm width and 180mm length are maintained, keeping dimensional compatibility within the 170mm PS3 footprint for airframes that can accommodate the additional pack depth.
For development teams evaluating the top end of the PS3 Series, this pack delivers the maximum energy available in a single-cell-string configuration: 634Wh at 28.8V with full PS3 cell quality and traceability.
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 FBC11071170PS3 8S1P is an 8S1P soft pack drone battery with a nominal capacity of 21,200mAh and a typical capacity of 22,000mAh. The nominal voltage is 28.8V based on a 3.6V per cell configuration across eight series cells. The pack delivers 634Wh of usable energy and weighs 2,296g, making it the highest-energy pack in the PS3 Series. Physical dimensions are 180mm length, 74mm width, and 94mm thickness, with a QS8-S discharge connector and JST-XHP-9P balance connector.
Both packs use the same FBC11071170PS3 170mm cell and share identical capacity at 21,200mAh nominal. The 8S1P adds two series cells, increasing the nominal voltage from 21.6V to 28.8V, the pack thickness from 71mm to 94mm, and the weight from 1,752g to 2,296g. Discharge current remains the same at 130A continuous and 180A burst, but the power output increases from 2,808W to 3,744W continuous and from 3,888W to 5,184W burst due to the higher voltage. The charge cut-off voltage increases from 25.2V to 33.6V, requiring an 8S-capable charger, and the balance connector changes from JST-XHP-7P to JST-XHP-9P.
The FBC11071170PS3 8S1P supports a continuous discharge of 130A over 60 seconds at 25°C and a burst of 180A for up to 10 seconds. At 28.8V nominal, this translates to 3,744W continuous discharge power and 5,184W burst power, making it the highest-power pack in the PS3 Series. For heavy-lift UAVs and high-demand drive systems, this combination of high voltage and high current capability covers the most demanding operational profiles in the range.
The FBC11071170PS3 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.
