660mAh-FPV-90C-751761

The DXF 660mAh 90C High-Voltage (LiHV) FPV Series (751761 cell footprint) is precision-designed for high-agility micro FPV racing drones, toothpick platforms, 2.5-inch micro freestyle quadcopters, micro 3D aerobatic airplanes, and light RC helicopters. Leveraging high-density LiHV cell chemistry with a 3.8V nominal and 4.35V peak per cell threshold, this series delivers higher motor RPM, instantaneous punchouts, and stable throttle authority across 1S (3.8V), 2S (7.6V), 3S (11.4V), 4S (15.2V), 5S (19.0V), and 6S (22.8V) configurations, eliminating mid-flight voltage sag during aggressive track cornering.

Key Features:

• High-Voltage (LiHV) Architecture: 3.8V nominal and 4.35V max charge voltage per cell unleash punchier motor acceleration and superior power-to-weight performance compared to conventional 3.7V batteries.
• High-Rate 90C Discharge Burst: Provides instant current response and consistent voltage stability under intense micro-drone race loads.
• Comprehensive 1S to 6S Configurations: Precision-assembled packs in 1S (3.8V), 2S (7.6V), 3S (11.4V), 4S (15.2V), 5S (19.0V), and 6S (22.8V) setups to suit various high-RPM brushless motors.
• Complete 7-Connector Compatibility: Factory-installed with PH2.0, JST, XT30, SM, XT60, EC5, or XT90 plugs for direct plug-and-fly installation without adapters.
• Ultra-Low Internal Resistance (IR): Stringent cell grading delivers balanced discharge curves, cooler operating temperatures, and dependable flight performance.
• Durable Silicone Leads & Reinforced Joints: High-strand-count silicone wire and robust internal solder joints resist high-G flight loads and tight canopy vibrations.
