Power Nano 33 BLE with 4s LIPO

Hello,

i want to power my Nano 33 BLE with a 4S Lipo (have it lying around catching dust). My shopping list looks like this:

  • voltage meter (to prevent deep discharge)
  • fuse (to prevent fire)
  • step down of some sort (14.6V to 3.3V or 5V) - thinking of a TRACO TSR2-2450 (is 5V but Nano 33 BLE can run on 5V)

Is my list complete or am i missing something? Any tips on products to choose would be nice (i will be using ggl to help me out there - but any help is always welcome).

Kind regards,

Bart
