Assuming there is nothing wrong with the connector it cannot contribute to overdischarging or puffing the pack. I say nothing wrong in that there is no intermittent shorting going on. That would cetrtainly cause over discharge and batt. damage.

Additionally, if you find the connector warm after flying then that would indicate some other issue causing excessive contact resistance resulting in heat during use. Then I would consider upgrading. I switched to ultra connectors because the new batts. come that way.
