A 150 amp BL ESC simply indicates that it can supply the motor attached to it with 150 constant/continuous amps. A 20C 3300mah 2S lipo battery is capable of a constant/continuous output of only 66 amps. Connecting 2 of these same batteries whether in series or parallel will still only provide 66 constant/continuous amps output.

If the motor in your rc car/truck draws more than 66 amps constant/continuous from the 20C 3300 lipos then your batteries will be destroyed. Lipo batteries will also be destroyed if they cannot provide the surge amp draw of the BL motor.

With the cost of lipos it is then well worth the time and effort to check the maximum constant/continuous and surge amp draw of your BL motor. Scroll to the near bottom of this link for an example-
