I received a SunControl board recently and attempted to use it to power a Raspberry Pi 3B+.
I connected the battery connection to a 1S4P set of Lithium Ion cells and the micro USB input to a 3A 5V wall wart. When I connected the USB A out to the pi, it starts to boot, but before making to the Desktop resets as if it's browning out. When I directly connect the 3A 5V wall wart to the Pi, it starts as expected.
Thoughts?

Picture attached. Am I using the wrong output to power the Pi? Or is it expected that if you want to run a Pi off this you'll need to add a cap? Or is SunControl the wrong product to do so? 1S4P refers to the battery configuration, which is 4 cells in parallel. Attachments:

Looks connected correctly.
As talked about in the articles above, you probably can't run a Raspberry Pi 3B+ or 4B from SunControl (1.0A continuous supply) without an external capacitor. It's the startup current that gets you.
When we are deploying Raspberry Pi 4Bs, we generally use SolarMAX2.
