How does the protection feature work?

The BMS of the battery pack with lock the output voltage to zero volts on a short circuit or under voltage conditions. Please charge the battery pack with an adapter or RPS (Shown below) to get the Battery Pack working again. 

The below graph shows how the battery pack handles itself in different loading conditions, namely at 500mA, 1A and 2A. As you can see in these conditions  the capacity of the pack is around 2150mah to 2220mah. 

Since the maximum operating voltage of the battery pack is 12.6V it can be used to power your 12V application.

Cell Balancing and Charging using Balance Connector?

The below image shows the battery pack being charged by a B3 Charger; this method uses the JST XH lead to balance charge the battery pack, ensuring maximum capacity.

How to charge this battery pack using adapter or RPS?

The battery pack can be charged and discharged using the same DC Jack connector. To charge the battery just connect it to a female DC barrel connector and provide 12.6V (4.2V per cell) to the positive pin and ground to the negative pin. Monitor the increase in the voltage with time and stop charging after the pack has reached more than 12.2V. Using RPS to charge the cell will provide better control and understanding.

Note: Lithium batteries can become unstable, if not handled properly, resulting in heat or fire. Safety precautions and prior knowledge is advised.
