In this episode of DIY or Buy I will have a look at a commercial solar battery charger. That means I will conduct a few tests with it and afterwards create my own DIY version that improves the functionality of such a solar battery charger. And after finishing testing the DIY boad, I will conclude whether DIY or Buy is the winner. Let's get started!
