LiPo (Lithium Polymer) batteries are a great way to power your portable projects (ideal for the Adafruit Feather!). Compared to other battery chemistries they're more compact, lighter and offer a consistent voltage output (rather than constantly dropping like other types!). They also offer higher rates of discharge which is ideal for high-power projects.

This is our smallest LiPo battery with a capacity of 150mAh (3.7V), with a 2-pin JST-PH connector on a ~100mm cable. Ideal for smaller projects and compact enough for wearables!

The batteries include internal protection against over-charging or under-voltage, which makes the battery out at around 3V. You should still use a dedicated LiPo charger with protection built-in - we recommend the Adafruit Micro Lipo as it has a convenient USB tail, a safe charge rate and a three-stage battery conditioning/charge cycle.

We have many other battery options in our Power section, including other chargers! These batteries are also available in 2000mAh, 1200mAh and 500mAh capacities.

Lithium Battery Shipping: Due to courier restrictions, this product can only be shipped within England/Wales. With this item in your cart, your shipping options will be limited to DHL. Why?

Always Check Polarity!

Not all devices follow the same polarity so always (always!) double-check the LiPo battery port polarity on your device before connecting a battery. If the polarity (+ and -) is different to the battery, consider switching the JST connector wires over.
