1850mAh-FPV-140C-853475

The DXF 1850mAh 140C FPV Series (853475 cell footprint) is custom-designed for aggressive freestyle pilots, long-range 5-inch to 7-inch FPV quadcopters, micro 3D aerobatic aircraft, and high-performance RC helicopters. Manufactured with automated cell stacking technology and ultra-pure lithium cobalt oxide chemistry, these high-capacity powerhouses deliver sustained flight times and an explosive 140C discharge burst to eliminate voltage sag during intense full-throttle punchouts and demanding maneuvers across 2S (7.4V), 3S (11.1V), 4S (14.8V), 5S (18.5V), and 6S (22.2V) configurations.

Key Features:

• Explosive 140C Discharge Burst: Delivers instantaneous throttle response, rapid punchout acceleration, and rock-solid voltage stability under demanding aerial loads.
• 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 various micro and mid-sized brushless drivetrains.
• 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 ensures 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.

Usage & Safety Guidelines:

• Charge exclusively with 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:

DXF provides a comprehensive 180-day limited warranty covering factory workmanship and material defects. Please inspect individual cell voltages and pack balance upon receipt before initial cycling.
