Lithium Ion Cylindrical Battery - 3.7v 2200mAh

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.
