I am just buying some LiPos (3.6V) and charging circuits for a project. The batteries come with overheating, over-voltage, over- and undercharging protection circuitry. In the reviews, someone mentions that you can use any source to charge it due to the protection. I googled it but it seems people make a difference between protection and charging circuitry, and I cannot find an example of someone using it without charger. I see why, but wonder if a protective circuit would work as a make-shift charging circuit, at least it won't explode, right?
In short, can I just hook the battery on the Vin on my D1 mini, supply the board from battery and charge the battery when hooking the board onto USB?
