Charging two 3S batteries using a single charging port.

Preferably using matched batteries with similar capacities, C rating, initial voltages.

Can also use a multiple balance board, using both 3S and 6S connectors, battery with GND lead using the 3S, and the battery with + lead using the 4 pins of the 6S on the left (looking at the board’s JST-XH connector with the notches on top).
