At the 1:30 mark the person in the video removes a new plug from the packaging and solders it to the onboard power supply plug. What is the name of this plug and any idea where I can get it?

this similar to the jst plug i think its called molex connector
try electronics shops

It's not a Molex

In fact I too have been searching for this for my Hitec Radio - I'm making a spare LSD NiMH battery pack.

Would appreciate any further info

If anyone interested we could combine orders to share shipping cost
