The DXF 1550mAh 140C FPV Series (653968 cell footprint) is engineered specifically for competitive freestyle pilots, 4-inch to 5-inch FPV racing quadcopters, high-speed micro 3D airplanes, and agile aerobatic RC helicopters. Utilizing premium automated cell stacking technology and ultra-pure lithium cobalt oxide chemistry, these lightweight, robust packs deliver a relentless 140C discharge burst to eliminate voltage sag during intense punchouts, split-S dives, and sharp power loops across 2S (7.4V), 3S (11.1V), 4S (14.8V), 5S (18.5V), and 6S (22.2V) configurations.
Key Features:
- Powerful 140C Discharge Burst: Provides instantaneous throttle response and dependable voltage retention under severe aerial racing demands.
- Comprehensive 2S to 6S Configurations: Precision-matched packs available in 2S (7.4V), 3S (11.1V), 4S (14.8V), 5S (18.5V), and 6S (22.2V) to pair seamlessly with diverse brushless motor setups.
- Complete 7-Connector Offering: Factory pre-soldered with connectors including PH2.0, JST, XT30, SM, XT60, EC5, and XT90 for direct plug-and-fly installation without adapters.
- Ultra-Low Internal Resistance (IR): Precision cell matching guarantees balanced discharge curves, cooler running temperatures, and prolonged flight endurance.
- High-Flex Heat-Resistant Wiring: Reinforced with heavy-gauge silicone leads and sturdy solder terminals built to endure severe flight vibration and high-G forces.
