Adafruit Lithium Ion Battery - 3.7V 10050mAh (10 Ah)

Lithium-ion batteries offer a unique combination of thin, light construction and impressive power output, making them an efficient energy solution. With an output ranging from 4.2V when fully charged to 3.7V, these batteries are designed for high performance.

This particular model boasts a capacity of 10,050mAh, delivering approximately 37Wh. Utilizing higher-density 18650 cells, it provides powerful energy storage in a compact package, similar in size to a 6600 power pack. Pre-attached with high-quality JST-compatible connectors, the battery ensures smooth and reliable connection without cable snags.

Rated for currents up to 2A, these batteries include built-in protection circuitry to prevent over-charging and over-use, maintaining safety by cutting out at 3.0V. Protection is also in place against output shorts, although it's crucial to use a LiIon/LiPoly constant-voltage/constant-current charger at rates of 3000mA or less, without unattended use.

Designed with the expert in mind, these batteries match Adafruit LiPoly/LiIon chargers and boards in polarity, avoiding potential destruction from reverse polarity. As with all Lithium-ion polymer batteries, careful and knowledgeable handling is a must.
