The FBC11671125PS3 6S1P is a high-discharge soft pack drone battery from the ampKRAFT PS3 Series, built on the 125mm cell format. With a nominal capacity of 16,000mAh (typical 16,700mAh) and a nominal voltage of 21.6V, it delivers 361Wh of usable energy at a pack weight of 1,350g.
What distinguishes this pack within the 125mm PS3 range is its continuous discharge capability of 130A, matching the performance of the larger 170mm format cells while staying within the compact 135.5mm length and 74.5mm thickness. For UAV engineers who need 130A continuous current but are constrained to a shorter pack form factor, this is the only 125mm option in the PS3 Series that reaches that current level.
At 1,350g and 361Wh, this 21.6V drone battery delivers a strong combination of capacity and current output for platforms with demanding power profiles in a weight-constrained airframe. 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, this pack bridges the gap between the 15000mAh variant at 120A continuous and the 170mm format cells, offering a meaningful current upgrade within the same 125mm cell footprint.
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.
Everything you need to know about the FBC11671125PS3 6S1P soft pack battery. If your question is not covered here, our engineering team is happy to help directly.
The FBC11671125PS3 6S1P is a 6S1P soft pack drone battery with a nominal capacity of 16,000mAh and a typical capacity of 16,700mAh. The nominal voltage is 21.6V based on a 3.6V per cell configuration. The pack delivers 361Wh of usable energy and weighs 1,350g. Physical dimensions are 135.5mm length, 74mm width, and 74.5mm thickness, with a QS8-S discharge connector and JST-XHP-7P balance connector. It is the highest-current pack in the 125mm PS3 format, delivering 130A continuous discharge within the compact cell footprint.
Both packs use the 125mm PS3 cell format and share the same 21.6V nominal voltage, 74mm width, and 135.5mm length. The 16700mAh variant adds 118g and 6mm of thickness compared to the 15000mAh pack, while increasing capacity by 1,600mAh nominal and stepping up continuous discharge from 120A to 130A. For platforms where the airframe accommodates the additional 6mm of pack depth and the higher current draw is relevant to the motor and ESC specification, the 16700mAh variant is the direct performance upgrade within the same cell footprint.
The FBC11671125PS3 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. This makes it the highest-current option in the 125mm PS3 format, matching the continuous discharge capability of the larger 170mm cells while staying within the shorter 135.5mm cell length.
The FBC11671125PS3 6S1P 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.
