I bought a litle [T-A7670X] and do project success. but i have big problem

  1. My project read sensor and alert to server my MQTT
  2. I have PIN 18650 into T-A7670X
  3. Power 5VDC to DC jack
  4. Power switch to ON
  5. TEST CASE
  6. DC (5V) connect to DC jack and device work well
  7. Unplug DC (5V) and device work by PIN 18650 and working 12hour, PIN is empty and i DO NOT plug DC (5V) and stay for 24hour later
  8. after 24h, i plug DC (5V) to DC jack, board is not work (SIM T-A7670X LED is not work, ESP 32 not run).
  9. Board is worked only when i switch power SW to OFF and wait 10 minute and back to ON
  10. IF i plug DC 5v to c-type, board work BUT when I unplug DC, board auto restart and used PIN 18650 Please advice me. I want board auto switch to battery when DC 5V off and auto switch to DC when DC 5v ON (DC 5V off for 48h).
