Adafruit Lithium Ion Battery - 3.7V 2000mAh

Lithium-ion polymer batteries offer a clever blend of slim design, lightweight structure, and impressive power. Their output fluctuates between 4.2V when fully charged to 3.7V, catering perfectly to a vast array of portable devices.

The 2000mAh capacity ensures prolonged usage, while a genuine 2-pin JST-PH connector guarantees flawless connectivity, reducing risks of snagging or jamming. Pre-installed protection circuitry prevents overcharging or overuse by cutting power at 3.0V and shielding against output shorts.

For optimal charging, use a LiIon/LiPoly constant-voltage/constant-current charger, ideally at a 2A or lower rate, though 500mA is best. The Micro Lipo charger, with its 100mA default rate, ensures safe recharging, switchable to 500mA for faster charging convenience. Alas, these batteries come without thermistors, advising caution with a 100 to 500mA charging rate.

Adhere strictly to safety precautions: avoid misuse such as shorting, bending, crushing, or puncturing. Do not leave unattended during charge or use, and frequently check for signs of damage or potentially hazardous circuitry. Compatibility with Adafruit chargers and boards is assured, though caution with other brands is necessary due to potential polarity issues.
