550mAh-FPV-90C-631761

The DXF 550mAh 90C FPV Series (631761 cell footprint) is custom-engineered for ultralight micro FPV racing drones, toothpicks, brushless whoops, 2-inch to 2.5-inch freestyle quadcopters, micro 3D airplanes, and micro RC helicopters. Crafted with automated cell stacking technology and premium lithium cobalt oxide chemistry, these compact packs deliver an agile 90C discharge burst to provide immediate throttle response and prevent voltage drop during aggressive punchouts, tight course maneuvers, and rapid flips across 1S (3.7V), 2S (7.4V), 3S (11.1V), 4S (14.8V), 5S (18.5V), and 6S (22.2V) configurations.

Key Features:

• Agile 90C Discharge Capability: Supplies instantaneous throttle punch and sustained voltage under heavy micro-drone aerobatic loads.
• Comprehensive 1S to 6S Configurations: Precision-matched packs available in 1S (3.7V), 2S (7.4V), 3S (11.1V), 4S (14.8V), 5S (18.5V), and 6S (22.2V) setups to pair seamlessly with diverse micro brushless power systems.
• Complete 7-Connector Offering: Factory pre-soldered with PH2.0, JST, XT30, SM, XT60, EC5, or XT90 plugs for clean plug-and-fly compatibility without bulky adapters.
• Ultra-Low Internal Resistance (IR): Stringent cell grading delivers balanced discharge curves, cooler running temperatures, and dependable flight performance.
• High-Flex Heat-Resistant Wiring: Reinforced silicone leads and robust internal solder terminals built to endure heavy flight vibration and compact canopy geometries.

Usage & Safety Guidelines:

• Always utilize a certified microprocessor balance charger set to LiPo balance mode (max 4.20V per cell).
• Always place batteries inside a fireproof LiPo safety charging bag on a heat-resistant surface while charging.
• Charge strictly at 1C or lower (never exceed recommended charge rates).
• Never discharge below 3.2V per cell, and never leave charging batteries unattended.
• Store batteries at 3.80V–3.85V per cell storage voltage in a cool, dry, well-ventilated space.

180-Day Manufacturer Warranty:
