Power requirements?

I have purchased one of these Phats

https://www.sparkfun.com/products/16475

And have the touch screen and Pi4.

I keep getting low power warnings.

What kind of supply do I need. I am trying to run this from a 48volt golf

cart with a 12v converter that then runs a 5v converter.

DC 12V/24V/36V to DC 5V (Accept DC 8-40V Inputs) Truck Car Step Down Power

Adapter Converter Reducer Regulator for Auto Electronics Vehicle Boat Solar

System - 10A 50W

How many Amps / Watts do I need?

Please advise.

Thanks,

The Pi will use up to 3a, plus any peripherals you add to the pHat…but it needs to be regulated too.

Get a regulated 5v 4a power supply and you should be all set
