By far, the most popular option for adding a Lithium battery in a DIY project is to utilize a simple charger breakout module. These often-tiny modules offer a fantastic mix between flexibility, safety, and cost-efficiency, and they are typically remarkably easy to use.
Power Your Arduino Project with a Lithium Battery So far, this series of articles have investigated common battery technologies, the tasks of battery management systems, and how to charge Lithium batteries correctly. This article summarizes a few options makers have when powering an Arduino-based project off a single 18650 Lithium-Ion battery cell.
Many of our projects are running off the common 18650 Lithium Ion battery, so today we wanted to talk about the math of charging, and of course we want to use an Arduino to manage that charge. Lithium Ion batteries need a Constant Current (CC) / Constant Voltage (CV) charge.
Assembling the Battery Pack Once you have all the necessary tools and materials, it's time to assemble your DIY lithium battery pack. Start by connecting the battery cells in series or parallel configuration, depending on the desired voltage and capacity. Use nickel strips or copper busbars to create secure connections between the cells.
Before diving into the world of DIY lithium batteries, it is essential to understand what they are and how they work. Lithium batteries are rechargeable batteries that utilize lithium ions to store and release electrical energy.
All this means that you can employ unprotected Lithium cells such as standard 18650 batteries in combination with common charge modules. Off-the-shelf battery modules are a good way to secure a project that uses batteries against common faults that might occur while charging or discharging a Lithium battery.
