I needed to pull power from the FBL unit to power a Scorpion RPM opto coupler but the only free port on the FBL was being used to power the fan on the ESC. This allows me to run two devices into one port without bulky soldered Y-splitter.

Soldering is LESS reliable than crimping.

I'm using a DuPont factory hand tool for 0.1 crimp terminals (HT-95), unlike e.g. the Hansen crimpers it's specifically made for this terminal type (Mini-PV terminals). According to the technical specs for this connector family two 26 or 28AWG wires are allowable in a single terminal.



Unlike generic tools this one wraps the insulation "wings" around so that they "hug" the wire and swages the conductor crimp into a tightly rolled tube. This is the way these terminals are actually supposed to be crimped, generic tools like the Hansens work but sort of mangle the terminal in the process. It also has a terminal locating mechanism that holds it in place in the tool so you only need to line up the wire in the terminal.

This was just a practice run with some scrap wire I had laying around I ordered some 26 AWG Radical RC wire which has tougher insulation (though this also make it a bit stiffer)
