Reply To: DC power question

I wouldn’t use an inexpensive buck converter as it would likely be RF noisy. You could drop about 2V using four silcon diodes in series. That would be RF quiet.

Can you monitor the output voltage from the battery pack to determine if it is dropping out or fluctuating after the time-out period? Check that it is charging up fully vs. being almost depleted. And can it handle the current level that is required (meaning does it have a battery management system [BMS]) that might be shutting it down on overload)?

I am curious. What is the required current?
