Hello, on the https://www.openacousticdevices.info/sd-card-guide SD card guide you provided it gives the mA of multiple different SD cards. I am trying to record for an extended period of time and trying to do the math on when I need to replace SD cards and batteries. Is the battery consumption from large SD cards daily or in total, and how negligible is it?

Hi Wulfgar, The Config App will tell you the estimated daily energy consumption of the configuration that you have set.
This is calculated assuming a SanDisk Extreme 32GB card. If you use a different card you can just scale the energy consumption by the ratio of the average current shown in the table at the appropriate sample rate and that will give you a good estimate for the other card. For example, the schedule above shows 95mAh per day with a SanDisk Extreme 32GB card. If I use a Samsung Evo Plus 64GB card, I'd expect the daily energy consumption to be about 95 x 22.2 / 12.3 = 172mAh. Alex
