The ASOL783945-3S is a premium Li-Polymer battery pack using three flat 783945 soft pouch cells in 3S1P series configuration, delivering a stable 11.1V nominal voltage and 1700mAh capacity (18.87Wh). The 783945 Li-Po cell format (7.8mm thick × 39mm wide × 45mm long) provides an outstanding balance of energy density, ultra-light weight, and compact footprint — the preferred choice for performance-driven RC and drone applications where every gram of weight savings translates directly into longer flight times, faster acceleration, and sharper handling.
11.1V (3S) is one of the most widely adopted voltage standards in the FPV drone, RC aircraft, and high-performance RC vehicle markets. With 1700mAh capacity, the ASOL783945-3S delivers competitive runtime: 8–15 minutes of aggressive FPV racing flight, 15–25 minutes of steady RC airplane cruising, and 15–30 minutes of continuous high-speed RC car operation. The lightweight Li-Po construction keeps total aircraft or vehicle weight low, which means less strain on motors and ESCs, cooler operating temperatures, and more responsive control.
Each pack incorporates a built-in PCB protection circuit guarding against overcharge, over-discharge, overcurrent, and short circuit. Every unit is manufactured at our ISO-certified facility and passes 100% outgoing QC: open-circuit voltage verification, capacity discharge testing, and protection circuit function check before shipment. Grade-A Li-Po cells are voltage-matched within ±10mV to ensure stable series operation and uniform cycle aging.

Application Scenarios
1. FPV Racing Drones & Freestyle Quads
11.1V (3S) is the dominant voltage standard for FPV racing drones, freestyle quadcopters, and mini quads worldwide. With 1700mAh on tap, pilots get 8–15 minutes of flight time depending on flying style and motor setup — enough for a full heat of competitive racing or an extended freestyle session. The ultra-light soft pouch cell construction keeps the aircraft’s all-up weight minimal, which translates directly into sharper turns, faster acceleration, and more air time per charge compared to heavier cylindrical cell packs.
2. RC Airplanes & Fixed-Wing Aircraft
11.1V is the sweet-spot voltage for small to mid-size RC airplanes, gliders, and fixed-wing aircraft with brushless motors. The 1700mAh capacity delivers 15–25 minutes of steady cruising flight — plenty for a relaxing afternoon at the field. The compact soft pouch cell pack fits neatly into standard fuselage battery compartments without shifting the center of gravity, keeping the aircraft stable and predictable in flight, whether you are doing gentle circuits or aggressive aerobatics.
3. High-Speed RC Cars, RC Trucks & RC Buggies
11.1V 3S Li-Po is one of the most popular power configurations for high-performance RC cars, RC trucks, and RC buggies on the market today. At 1700mAh, drivers get 15–30 minutes of fast-paced track action on a single charge. The lightweight Li-Po construction keeps the vehicle’s center of gravity low for better cornering grip and faster straight-line acceleration, while the compact pack fits standard 1/10 and 1/12 scale chassis battery trays without any modifications needed.
4. Small Robots, Educational Robotics & AI Car Platforms
11.1V is a widely adopted voltage for small robotics platforms, educational robots, STEM kits, and AI car development boards. The 1700mAh capacity provides hours of extended runtime for autonomous navigation systems, sensor arrays, and motor drive systems — enough for a full day of classroom demonstrations or weekend maker sessions without interruption. The slim soft pouch cell pack integrates cleanly into robot chassis and AI car frames, leaving plenty of room for controllers, sensors, cameras, and other peripherals.
Why Choose Li-Polymer Over Cylindrical Li-ion Cells?
For FPV drones, RC aircraft, and high-performance RC vehicles, the choice of battery format directly impacts flight time, speed, and handling. Here is a side-by-side comparison:

| Thickness | ~28mm (slim) | ~38mm (4 cells side by side) |
| Discharge Rate | Up to 3C continuous, 5C burst | Typically 1C–2C |
| Shape | Flat — fits slim compartments | Cylindrical — needs round cell holders |
| Form Factor Flexibility | Custom dimensions possible | Fixed 18×65mm cell size |
| Capacity | 1700mAh | 2000–2600mAh (higher) |
| Energy | 18.87Wh | 22.2–28.9Wh (higher) |
| Cycle Life | ≥500 cycles | ≥500 cycles |
| Weight Advantage | 30–40% lighter | Heavier |
Choose 783945-3S Li-Po when: Weight, thin profile, high discharge rate, and form factor flexibility are critical — ideal for FPV racing drones, RC airplanes, and high-performance RC vehicles.
Choose 18650-3S when: Maximum capacity and longer runtime in a larger form factor are acceptable, and the mature cylindrical supply chain is a priority.
