This would be approach 1. If you would like to get a more precise information on your battery, you could solder the battery + via an voltage devider to the ESP Analog input. (The esp pin will not accept a voltage greater than 3,3V on its analog in). You will have to measure the battery voltage then and compare it to the voltage the ESP measures.

It can be quite confusing to get the pin numbers correct. For an UNO based form factor, IMO, the D1 (not the D1 R2) is a better choice. On the esp8266 platform. a naked constant like 7 or 6 specify a GPIO bit number. If you have an UNO type form factor board like a D1 or a D1 R2 board you cannot use naked constants like you used on a UNO board.
Wemos D1 R2 power. Using Arduino Project Guidance. AJLeoncio March 24, 2019, 10:59am 1. Hi! this is my first post in the community and i would like some help with my capstone project. i am making a mobile light trap with LED's and a wemos module. my main power supply would be a 12v motorcycle battery, i've tested the LED's and they're working
