Hi,
Is it possible to power Audiomoths with 6V lead batteries via USB port, or would it damage them (almost 7V when fully charged)? I've been looking for a way to power them with a rechargeable high capacity power source. The idea is to avoid soldering cables onto the board/removing the battery-holders, to keep things simple for future users. I've also tested connecting lead batteries via AA battery sized dummies (wood + nails + cables), but this results in noise between 65 and 75 kHz.
All the best

Hi, thank you for the quick reply! So far I only used 2 dummies, that only have a connection to the battery case at one end. Could that have caused the problem?
In the picture the dummies are inserted at the wrong place, this was just to see if they fit at all. The black end would sit where the battery case is connected to where "-" is on the board, and the red end would sit below "+". So both dummies turned around and switched.
