Using an 18650 Battery with TTGO ESP32 SX1276 Microcontroller

Hi all, Been trying to use a 18650 rechargeable lithium ion battery with my TTGO ESP32 SX1276 microcontroller and not having much luck. TTGO does not seem to want to be powered by the battery. From my understanding I thought that if you plug in the TTGO via micro USB it simply charged the battery and you are good to go, but it doesn’t seem to be the case with my testing. Has anyone had any experience with powering this board using a battery? If so, could you please tell me what you had to do

ESP32 SX1276 LED turns on when entering deep sleep using micropython. Is this expected behaviour? It's for a battery powered project and I want to reduce power usage. Should I even care
