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

Luisa
