HIFIBERRY AMP2 with standard power supply and Boost Step-up transformer

Hi,

I was wondering.

I want to create a battery operated configuration using the PiJuice HAT.

The problem I can foresee with this setup is that the HIFIBERRY AMP2 requires more power.

I was thinking to use some sort of Step-up transformer to take the power from the PiJuice HAT and power the HIFIBERRY AMP2 HAT/module.

But I am thinking now it perhaps by doing this I might not be creating a short between the Raspberry Pi + PiJuice HAT and the HIFIBERRY AMP2 through the GPIO headers.

Should I use instead a separate battery setup something that can offer the required power for the HIFIBERRY AMP2? this would be a shame because it would slightly increase the complexity of the setup.

Could you advise and point me to where I can get this information?

Thanks,

That doesn't make much sense. Even if you would use a step-up-converter, the Pi/Amp2 would probably only run a few minutes on a small battery like this. For a battery powered device, get a LiIon battery in the range of 12-20V and a battery controller that handles charge/discharge /discharge is especially important as you need to make sure never to fully discharge a LiIon battery).
