How would I go about including a 7.4v 2S LiPo battery with integrated charging in my project? The ideal situation for me would be to have the battery and charging in the project so that I could just connect a USB or barrel jack connector for charging without having to remove the battery to charge it.
This is the sort of battery I had in mind:
I just can't seem to find any sort of PCB solution to charging batteries like this. I can only find boards that charge 3.7v single-cell LiPo batteries. Like this:
The other thing I have found is boards like this:
But that seems to only be a protection board for 18650 Li-Ion cells and doesn't actually appear to be for charging the batteries.
If I were to use a 2S protection board like that, would I just connect the centre terminal of the balance plug to the MB terminal on the board? How would I then go about actually charging up the batteries?
Any help would be appreciated.
