I had a conversation recently with a user testing the trial device regarding changing the default sampling rates selectable via the config software. They were keen to record at a sampling rate of 384Khz. I thought I'd therefore open a thread on the forum to allow the AudioMoth team to reply with a little more information regarding what's possible with the current device, as I believe at present 222KHz - 240KHz with short buffer recordings is the max to retain stability (and SD write speeds / cart types also need to be accounted for).
I have seen two posts on this forum regarding rechargeable batteries. I am currently thinking about investing in purchasing 1.2V Envee 2800mAH rechargeable batteries, as I will be creating much lesser electronic waste compared to purchasing regular alkaline batteries. Apart from operating at the lowest threshold for the Audiomoth's, has anyone used rechargeable batteries for a while now? How does it affect the performance? Did you have to replace them every few days? Any issues with writing data to the SD Card?
