I would like to power the MDBT42Q through a battery which is connected to a charger. I tried to connect the charger pins (5V & GND) to to pins of the MDBT42Q (GND, V+), which are used if I would connect to battery directly. Unfortunately the board does not react. Is it possible to power the board over the recharger?
When I connect it to the Bat and GND pin, it seems to work. Is this the right connection? And where does the other pin stands for?
Here are some illustrations of the connections:
