Unfortunately both your voltage and current sensing methods each require an analog pin, of which an ESP8266 only has one. So if you want to make full use, then you need to either add in a ADC multiplexor, change to an ESP32 with multiple ADC ports or use a different sensor like the INA219 that runs on i2C and will read both voltage and current as well as being much more accurate than the ACS712.

I have used both for similar monitoring of a battery and charge… and a bunch of other stuff…
