UPS HAT E for Raspberry Pi 5 - 21700 Battery Board

Keep a compatible Raspberry Pi powered through an external-supply interruption with a UPS expansion board that charges its batteries while supplying the computer.

✅ Bridge an external power interruption - The board switches to fitted batteries when its external power source becomes unavailable.

✅ Monitor the power system in software - I2C communication exposes battery and Type-C operating information to your application.

✅ Power the Pi through pogo pins - The connector arrangement supplies compatible Raspberry Pi boards without occupying GPIO resources.

✅ Recharge while the system operates - Type-C charging and power output can run together with a suitable supply.

Build power continuity into your Pi project

A Raspberry Pi project can lose more than its current screen when power disappears. This UPS HAT provides battery-backed power, giving a correctly configured system a way to keep running or prepare an orderly shutdown.

The onboard fuel gauge provides voltage, current, power and remaining-capacity information. Your software can use those readings to decide when to save work and shut down; installing the board alone does not create that shutdown routine.

Four compatible 21700 lithium batteries are required separately. Use matched cells of the correct specification and polarity, and follow the board's battery and charging instructions when assembling the power system.
