I just made/assembled myself a cheap DIY 12V UPS or battery pack anyone can setup.
Thank you for the information.
Is there please a list of which materials were used? I am particularly interested in the power cable.
Thank you very much already.
The cable and adapter I used are usb male to 5.5x2.1mm male power cable. And usb to usb c adapter. Both of which can be found in a chinese online store for cheap… i just connected those to complete the power cable for the larkbox. My UPS is made of pre made UPS system. Its basically 3S2P BMS style… and the batteries i used are the ones i salvaged from my old laptop.
Thank you very much.
