Tools: Wire cutter/stripper. Soldering iron. Helping hand (optional) Screwdriver mAh Battery Life Calculator is an online tool used in electrical engineering to precisely calculate battery life. Generally, battery life is calculated based on the current rating in milli Ampere per Hour and it is abbreviated as mAh. Ampere is an electrical unit used to measure the current flow towards the load. With li-ion and li-po, the voltage when fully charged is 4.2V, which is too high for the esp chip, so a voltage regulator will be needed. To maximise battery life, this should be a low-dropout regulator. Unfortunately, the regulator on the nodeMCU boards is not a low-dropout, so you would need to bypass it. Also note that using what looks suspiciously like a 9v transistor radio battery to power a "solenoid" is going to be a mistake. Buy a proper FET with a threshold voltage less than half of what you can apply and data sheet performance indicating low loss in your actual gate voltage, and temperature conditions. Another option is to increase the battery life, by using an Arduino Pro Mini running on 3.3V/8MHz with an ESP-01. If you want to go a big step further you could also build an automatic watering system using a water pump! With a ten year shelf life, these batteries are ready for any occasion.
