Adafruit Lithium Ion Cylindrical Battery - 3.7v 2200mAh

This lithium-ion battery offers a robust 2200mAh capacity, complete with a protection circuit that safeguards against over-voltage, under-voltage, and over-current scenarios, ensuring longevity and performance. Its slim design integrates seamlessly into a variety of project cases.

With a peak current provision of up to 2 C (4400mA), this battery efficiently supports high-demand tasks, although it is recommended to maintain a constant current draw below 0.5 C (1 Amp) for optimal functioning. The pre-attached 2-pin JST-PH connector ensures a secure and smooth connection, preventing cable snagging.

The integrated protection circuitry cuts off power when voltage drops to 2.5V, defending against overcharging and complete discharge. For recharging, employ only a LiIon/LiPoly constant-voltage/constant-current charger at a rate of 0.5 C (1 Amp) or lower to preserve the battery's health.

Notably, the battery lacks a built-in thermistor, necessitating a cautious charging rate of 1/2 C or less. Standard safety practices should be observed, such as avoiding the use of incompatible chargers and inspecting for potential short circuits or damages regularly. Pros can take advantage of polarity compatibility with Adafruit LiPoly/LiIon chargers.
