I Would like to monitor

Use a Node MCU Board

5 DS1822 water proof Sensors

From experience using the NODE MCU board running a logging system updateing a BLYNK server every 2 seconds a 12V 12AH SLA last about a week.

I dont think I need that kind of resolution so will initially set the update rate to once every 15minutes and put the ESP8266 to sleep between updates. As I will me monitoring the battery voltage I will be able to reasses the energy requirements once I start to obtain real data
