Does someone know the part number for the battery connector on the RK3399? Im trying to buy/make a battery pack compatible with the OrangePi RK3399.   Alternatively, anyone knows where I could find battery packs with that connector?

I've explored the schematics and the datasheet of the bq25700 (TI's battery management chip), awesome chip btw, but I'm not sure if it charges the battery with USB-C power (5V).
The bq25700 should step-up the voltage to charge the 7.4V spec battery. I'm missing the connector for the battery, anyone has tried this functionality?

Ok, so I soldered a 7.4V battery to the connector and powered via USB-C and it would seem to charge, however, when i connect and disconnect the battery while powered, the leds change intensity, not sure what this implies.

For anyone looking, i've been searching for compatible connectors and I ordered some of these : Molex 51021-0700, I'll let you know if they are compatible.

The other connectors on this board are JST, so I think the battery connector could be a JST, not a molex...
