The use of vehicles and renewable energy systems is becoming more popular and this means we need better ways to manage batteries. Old ways of checking batteries are not good enough because they do not work in time and you cannot check them from far away. This can cause problems like batteries getting too hot or overcharged which can make them last for a time. This project is about making a system to check batteries using a small computer called ESP8266 NodeMCU. The system checks things like how much power is in the battery the temperature, how humid it is and how healthy the battery is. It sends all this information to a website called Blynk so we can check everything from anywhere. The system also has special safety features like turning off the battery if something goes wrong and making a noise to alert us. We tested the system. It works much better than old systems. It is also cheap. Can be used for many things, like electric vehicles and storing energy.
