How to power a RaspberryPi from a battery connected to USB-C?

My intention is to power a RaspberryPi from a battery for a robot that I am working on.

Currently, I am using a 7.4V battery, based on motor requirements. I’d like to be able to drive the RaspberryPi from the same batter, if possible. This USB power converter: https://www.amazon.com/Type-C-Step-Down … 4TWKHDD0RF

looks like a good fit, but it requires 12 V. Is anyone here familiar with anything similar? I assume I am not the first person to use RaspberryPi with a battery.

You’re going to need a DC to DC converter that works at 7.4 volts and is able to provide 5 volts at 3 amps. SparkFun doesn’t carry one but Pololu has some that should work. Have a look at the part in the link below, I think that would probably work for you.

    Thanks. I found this USB-A DC-DC “buck” converter:

    Going to try that along with a USB-A to USB-C cable. This way I can avoid having to solder to the USB-C pins.
