TS v1.0 Battery powered #15

Hello, I'm feeding the TS v1.0 with a 18650 connected using the supplied little power cable. The battery can be charged using the Micro USB port with no problem. The Comunication with PC is pretty good and the SW loaded on ESP32 runs fine when powered via USB. My issue is that when power is supplied by the battery the unit hangs/reboot/crash with the battery level lower than 3.9v! Even with fresh charged battery, the screen light dims on every task, such play a beep on the speaker, read a value from ADC, reading from SD card,etc. Does anyone also experience this issue? Is there anything I could do to fix its power stability?

BR, Nuno

Hi, I have Version 1.2 with 1.4" display and MPU. I am running the board with a 3.7V 1500mAh Lipo and it workes find for me, no crashes on beep, display changes or on any other current consuming action. I have currently not checked with SD card but will do today. I Read a bout a problem where they build in a fuse instead of a diaod but this should only influence the loading, which seems to be not the case. BR SFA
