Short Circuit Protection Using Relay For Batteries

In this tutorial, we will see how to make a short circuit protection using Relay. Many times accidentally terminals of batteries and other power supplies get short-circuited. Due to this, they get hot and start degrading. In the case of lithium-ion or lithium-polymer batteries, they may catch fire due to short-circuit or even get blast. […]
