I am interested to add solar panels to my AudioMoths but also retain batteries so that in low light conditions it won't lose power and then in theory it can be deployed until the SD card is full. I know from other posts that a solar panel can simply to plugged into the USB, will this over-ride the power source from the batteries? If there is no power coming from the solar panels can the AudioMoth then use the batteries?
Ideally I see a solution where the batteries are being charged by the solar panel and the AudioMoth is being charged by the batteries rather than the solar panel. Has anyone tried to do this? Or does anyone have any suggestions as to how to do this?
I think that install solar panels in the audiomoth is not necessary, and maybe do the thieves work easy...
You can put some 18650 battery and take all the recording time you want... I record all the night, 1 month with one 4 battery pack.
If you want to record more time you only need more 18650. Two moths with 8 batteries are possible. You only need a very great sd capacity
These are one option:
