If you need to cut the connector off a LiPo to fit a different one DO NOT just get a pair of wire cutters and cut through both wires at once
When I first started working I worked as a draftsman at a machine shop, we did work for NASA.
One job we had was building a "Wing Vortex Vehicle" which had an Oldsmobile engine, battery, etc mounted inside.
The machinist making the mount for the battery took his tape measure to measure the distance between the 2 battery terminals,
and he touched them with the METAL tape measure.
Shoulda seen the look on his face, as the end fell off, followed by the piece between the battery posts,
then the rest of it reeling back inside the housing!!!
