## Description

A 3.7V 2,200 mAh lithium-ion cylindrical battery with built-in protection circuitry for over-voltage, under-voltage, and over-current protection. Slim enough to fit into many project enclosures and includes a JST 2-pin cable with a genuine JST connector for smooth, snag-free connections. The battery can deliver up to 2C peak current (4,400 mA), though sustained draws should be kept under 0.5C (approximately 1 A). The protection circuit cuts output at 2.5V to prevent over-discharge. Key Features 2,200 mAh Capacity – Plenty of power for portable projects Built-In Protection – Over-voltage, under-voltage, and over-current circuitry JST 2-Pin Cable Included – Genuine JST connector, rated for 2 A 3.7V Nominal – Standard lithium-ion voltage 2C Peak / 0.5C Sustained – Up to 4,400 mA peak, ~1 A recommended continuous Specifications Chemistry – Lithium Ion Nominal Voltage – 3.7V Capacity – 2,200 mAh Cut-Off Voltage – 2.5V Recommended Charge Rate – 0.5C (1 A) or less Connector – JST 2-pin (included) Safety Warning: Only use a LiIon/LiPoly constant-voltage/constant-current charger at 0.5C (1 A) or less. Do not use NiMH, NiCd, or lead-acid chargers. Never short, bend, crush, or puncture the battery. Never charge or use unattended. Always inspect batteries and surrounding circuitry for damage or loose wiring. Polarity matches Adafruit LiPoly/LiIon chargers — other brands may have reversed polarity. Ideal For Portable electronics and IoT devices Arduino and Raspberry Pi projects Wearable technology Battery-powered sensor nodes Package Contents 1× Lithium Ion Cylindrical Battery (3.7V, 2,200 mAh) 1× JST 2-Pin Cable
