Here's a 3.7V lipo battery on aliexpress. It clearly states it has a built-in protection circuit, but do I also need to externally provide a charging circuit, e.g. TP4056?
I asked them and the vendor was just as unclear as the page is. Either they don't know or it's lost in translation. After several rounds of questions, all I could get was a claim from they for me to "just use 5V and everything is fine".
I think I need a charging circuit and this is just a battery protection IC. What do you think?
