Early shut down of devices | openacousticdevices

Hello,

I have several issues with the AudioMoth, I don't know if they are inter connected or not

The first issued I had, is some Audiomoth had recording failure, it always happened at midnight and the record were cutting short of 1 to 3 secondes (not really a big deal). Then I had 3 audiomoth that stop after 10 days(instead of 14) and when I checked it turned on again but the AudioMoth Play showed :

Now I have several audio moth which start at almost full battery but it depleted really fast and stop after 3-4 days, here is an example : And the left the first day of recording and the right the last day it recorded.

And I also had some WAV files without any data.

I am using Kingston 64GB sd card and Varta ultra lithium 1,5V battery

And here is my config :

Firmware : AudioMoth-Firmware-Basic (1.9.0)

Time zone : UTC-4

Sample rate (Hz) : 48000

Gain : Medium

Sleep duration (s) : 300

Recording duration (s) : 60

Active recording periods : 1

Recording period 1 : 00:00 - 00:00 (UTC-4)

First recording date : ----------

Last recording date : ----------

Trigger type : -

Threshold setting : -

Minimum trigger duration (s) : -

Enable LED : Yes

Enable low-voltage cut-off : Yes

Is the low-voltage cut-off option responsible for the early shut down of the devices?

Thank you in advance for you anwser,
