  How do you power the E32-433T33D (E22-400T33D) using the battery. I would like to control the modules using Arduino Nano or ProMini?
  Thank you for your advice.
  Elkez.

  Hi Elkez,
  I usually use this solution
  Emergency power bank homemade
  
  The step-up drain current is from 18650 (you can put more than one in parallel), and the output is 600mha, which I think is sufficient to power the 400T33D, but check with the tester how much the current drains the device.
  
  Bye Renzo
