How Do You Make a Simple Battery Level Indicator
Building a battery level indicator doesn't have to be complicated. This guide walks you through using an ESP32 microcontroller, a voltage divider, and LEDs to create a reliable tool for keeping track of your battery's charge. Perfect for DIY enthusiasts, the instructions are simple and clear, making it easy to monitor battery levels effectively.
What causes BMS to fail
Battery Management Systems (BMS) are key to keeping batteries safe and working well, but sometimes they fail due to mistakes in design or setup errors. By understanding what causes these issues, we can fix them and make sure our batteries last longer and stay safe.
Is It Better To Store Lithium Batteries Charged or Uncharged
Storing lithium-ion batteries right can make a big difference in how long they last and how well they work. It's all about keeping them at the right charge level - not too high, not too low. Check out these tips to make sure you're storing your batteries safely and smartly.
How Does a Battery Level Indicator Work
Explore battery level indicators, those handy icons or numbers that show how much power you have left. Learn how they work, even when the battery's energy levels aren't straightforward, so you're always prepared to recharge.
How to Make a Simple Solar System At Home
Begin your adventure into solar power from home. Our guide simplifies the process of creating a solar system that suits you. Whether you prefer a standard setup or a simpler one, we'll walk you through it step by step.
Differences Between 18650 vs 38120
If you are looking to start on a new build you have probably came across 38120 cells they are different from 18650 cells in more than just size. They each have an ideal use case so it makes it pretty easy to pick which would be best for your build. We go over those differences and more in this article.
Nominal Voltage
Understanding nominal voltage and its importance when building, using, or buying a battery pack is crucial. This figure helps to interpret the voltage range of a battery pack or cell into a single number, which helps to simplify things. We go over nominal voltage in detail in this article and also touch on nominal voltage by common cell chemistries.
Disadvantages of Pouch Lithium Battery Cells
When building a battery pack choosing the best cell format often leads to cylindrical vs pouch cells. Each has its pros and cons to assess before choosing which will be used. One of the biggest questions is what are the main drawbacks of pouch-based LiPo cells. We go over that here!
What Are The Safest Lithium Battery Cells?
When building a battery pack safety is almost always the first thing to address. In this article, we go over the safety battery cell by chemistry and the considerations to decide which is right for your build. There are some trade-offs when it comes to making this decision so knowing all the factors makes the choice much easier.
