Use of 1.5V AA battery

[Ohlhues]

Dear forum,
I am working with a Raspberry pi zero 2 w and PiJuice zero. My project involves recording 30 seconds of video with the Raspberry pi HQ camera and illuminating an object with 6 IR diodes. My problem is that my 2500 mA battery can only power the system if the battery is fully charged. The IR diodes use 200 mA during recording and switch off afterwards. In addition, I also use an Adafruit MAX98357 I2S Class-D Mono Amp module. The Class-D module uses 0.9 Amp at 3.2W. So my question is.

Can I use 4 AA batteries instead of the PiJuice 2500 mA battery. Obviously it works on Vin, but can I also use the 3-pin connector on the PiJuice module?

Thanks in advance,

Sincerely
Anders
