No. That's an XT90 that will be inside the tube to connect the pack to the longer cable that then connects to the motor - still using the large Andersons to connect the battery tube to the motor.
It means that I can just disconnect the cable if I do this again in the future or I could make another pack that I could swap over quickly if necessary, without any soldering.
I'm toying with the idea of making a larger pack using 21700 cells which could give me more capacity than a standard P2 without the extra length.
