It should run with 4 x 18650 lithium battery cells, that can be recharged through USB Power Delivery 3.0 with up to 18W.

TIDA PowerPack is an open-source printed circuit board by janekc, from the janekc/TIDA-PowerPack repository on GitHub. It is a 4-layer board of 50 × 168 mm with 127 parts on 87 nets, routed with 594 tracks and 1,151 vias.
It is built around the TPS54531DDAR, SMTSO3015CTJ and BQ25798RQMR, with the CAT24C256WI-GT3, HOYLR2512-3W-3MR-1% and TLV75533PDBVR-MS among its other parts. Its parts include 56 capacitors, 35 resistors, 13 ICs, 3 inductors and 2 diodes.
This board is designed as a prototype for powering your projects using four 18650 lithium-ion battery cells. It delivers a 5V output with a maximum current of 5A. The cells are configured in a 4S1P (4-series, 1-parallel) arrangement, balanced and charged via USB-C Power Delivery (PD) with the maximum charging current supported by the cells. This design is based on the TIDA-050047 reference design by Texas Instruments.

Prototype for a time / location GNSS accessory for a Raspberry Pi 40-pin GPIO.

It measures 50 × 168 mm and has 4 copper layers, 1.6 mm thick.
127 parts, built around the TPS54531DDAR, SMTSO3015CTJ, BQ25798RQMR and CAT24C256WI-GT3. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the janekc/TIDA-PowerPack repository on GitHub, at the commit this page was made from: the board is TIDA-PowerPack.kicad_pcb and its schematic TIDA-PowerPack.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Its repository states no licence, so its author keeps all rights: ask janekc before reusing the design.
