RE: Adapting cell battery to HP 41
Hi,

Here the code of boards I used for this project.
They are used in Arduino projects and easily found in market.

03962A battery charger - this one has separeted outputs for battery and to the circuit to be energized;

MT3608A step-up converter

You can put such names on Ebay and it will bring tons of sellers.

I just have one doubt about my project: what will happen when battery discharge too much...
Best wishes!
