Battery pack.
This battery pack was made with the intention of it being a backup power system for a 12V router. The battery pack was designed with load-shedding in mind and as such it's a very small solution to load-shedding. This battery pack will allow your internet to stay on which should allow you to enjoy using your wifi for a couple of more hours.
This DIY battery pack can be a fun project that can teach you a lot of new skills, it will also give you more knowledge on batteries and how they work as well as how a BMS(Battery Management System) works.
We have a Lithium Battery Pack project, that shows you step by step how to build one.
