Hi, I am building and designing a power HAT for my Raspberry Pi 5, which will be installed inside a car. It will function as a satnav, ham radio programming computer, GPS tracker, and dashcam controller.
I want the Raspberry Pi to remain powered for 1-2 hours after the car engine is switched off. I've started drawing a schematic based on a 3-cell BMS IC and charger from TI. However, this approach requires some complexity in both software and design. I was wondering if perhaps I could use a single cell instead.
I bought a step-up module based on the LTC1871 IC, connected it to a 3.7V RC car battery, and then connected the module's output to the Raspberry Pi. It worked, and the Pi booted with no warnings. Is it a bad idea to run it off a single cell in the long run?
