Same config, same batteries, same SD, vastly different recording times? Audiomoth stopping recording after approx. 60 hours regular issue
I am having a recurring issue where my Audiomoths are stopping recording after only 60 hours at 48kHz. I believe it may be associated with the Enable low-voltage cut-off : Yes setting. Previously you could turn this off in the config, but now it is no longer an option? Below are two deployments with identical batteries, SD cards and configurations. Energiser Pro Max Plus Batteries, Sandisk Extreme 64GB cards. One records for only 58 hours, the other for 166 hours (the amount of time I would expect). This issue happened to me on almost 30 recorders in my last deployment, and I decided it must have been a bad batch of batteries (was using Varta) so I swapped to Energiser Pro Max Plus and the issue still persists. Any ideas why? Summary files and config attached. The early stoppage seems to occur when the battery drops to 3.5v, but this is happening far earlier than it should right? v1.2 Audiomoths. Previously have had no issues getting 160-180 hours out of normal alkaline batteries. Any advice appreciated, thank you!
Thanks for tracking this down. It's very fustrating as SanDisk Extreme cards have always been very reliable and low-energ in the past. GroupGets are checking their stock. The ones that they've looked at so far seem to be made in Malaysia. We'll try to get examples of all of them so we can measure their energy consumption.
