I have a lot of projects around the house that run off Raspberry Pi 3 or 4 single board computers. I have had my eye on a UPS designed and built for the Pi: https://lifepo4wered.com/lifepo4wered-pi+.html
This board is all setup to take solar as input to charge the UPS and run for up to 9 hours off the 1500 mAh LifePO4 cell (18650) for $55 plus $10 shipping.
That's not enough power for me. After watching Will's new video this morning (Cheapest Aliexpress LiFePO4 CALB Cell Reviewed), it has me thinking different options I would like to try ... and thoughts on the Pi. Does it make more sense to keep the batteries at 12V and use a DC-to-DC power supply to take the power down to the right level for a Pi? Should you run the batteries in parallel at 3.3V instead?
Is anyone out there running a Pi off of solar?
