Problem charging Electron, powered by LiPo connected to Li+

Hello there helpful community :smile:

I’ve encountered an issue charging my Electron’s LiPo battery when they are connected to Li+ & GND. The LiPos’ are only 1500mah, but when connecting them via JST, they seem to charge fine. Someone has a clue what’s wrong here?

Running 0.6.1rc-2 firmware btw!
