    Charging two 18650 in series with USB.

      I'm pretty much trying to make a 7.4V battery pack, however it is critical that it can be charged through USB (5V).

      So I have some 3000mAh LG cells, and that is pretty much it.

      However as that board needs 9V, I was thinking about boosting the 5V through this: Link

       

       

      I hope it is easy to understand. Please tell me if I risk burning down my house, as that would be less optimal.
