SMUGDESK UPS HAT 18650 Backup Board for Raspberry Pi 4

SKU CH-B5DZ-DKXBM

Provides uninterruptible backup power for Raspberry Pi 4 using 18650 batteries with intelligent protection and stackable HAT design

  • Designed exclusively for Raspberry Pi 4 stable backup
  • 18650 lithium battery delivers longlasting uninterrupted power
  • Builtin circuit protects against overcharge overdischarge shortcircuit
  • Stackable HAT installs easily without extra wiring
  • Ideal for home servers monitoring devices portable projects

Designed for Raspberry Pi 4

This UPS HAT expansion board delivers uninterrupted backup power to a Raspberry Pi 4 using 18650 lithium batteries. It stacks directly onto the GPIO header for a compact, wire-free fit. Integrated protection circuits guard against overcharge, overdischarge and short circuits.

Suits portable and always-on projects

Makers running home servers, remote monitors or mobile Pi rigs gain continuous operation during mains failures. The stack-on format keeps the footprint small inside tight enclosures. Builders needing power for boards other than the Raspberry Pi 4 must choose a different HAT.

Runs on 18650 cells

The board accepts standard 18650 batteries, letting you select capacity and replace cells when they age. No proprietary pack is required, so spares are easy to source. Remember to supply your own 18650 cells; none are included with the board.

Questions about this item

Does the SMUGDESK UPS HAT ship with 18650 cells or do I need to buy them separately?

The board uses 18650 batteries for backup power; cells are not included and must be purchased separately.

Which 18650 cell specification should I select for this UPS HAT?

Choose protected 18650 lithium cells with a built-in protection circuit; the on-board management handles overcharge, overdischarge and short-circuit safety.

How does the 18650 backup keep a Raspberry Pi 4 running during a mains outage?

When mains power fails the HAT switches to the 18650 cells instantly, supplying uninterrupted power so the Pi stays on without rebooting.
