This SHIM from the Pimoroni Pirates provides a convenient way of powering your Raspberry Pi Pico from a LiPo/LiIon battery. You can recharge the battery easily by providing power to the Pico's USB port, then take your Pico or Pico W project on the go with the battery pack powering your circuitry.

Solder this neat little square to the pins on the back of your Pico, plug in a suitable lithium-ion/polymer battery and tada - a LiPo Pico! The inbuilt charging circuit means you can recharge the attached battery by supplying power to the Pico via USB, and it includes protection against overdischarge and overcurrent.

There's a power button to stop the SHIM from providing battery power when it's not needed and turn your project on and off, as well as two LED indicators - a white one that shows when the shim is providing power and a red one to tell you when the battery is being charged.

Safety note! You should only use this SHIM with LiPo or LiIon batteries, and you should make sure that any project involving LiPos is sufficiently protected from being dented, bent, punctured, or crushed.
