Strip one lead to expose about 2-3mm of wire.
IMPORTANT NOTE: When installing Battery
connectors, be especially sure to strip, solder and
install one wire/connector at a time to prevent
the chance of an accidental short.
Using the soldering iron and solder, tin the
exposed end of the wire. Be sure to completely tin
the wire to avoid a possible cold or poor solder
Lightly tin the inside of the EC3 gold "bullet"
connector (try not to use too much solder in order
to prevent excess solder from flowing to the
outside of the bullet connector in the next step).
Note that the female "tubes" are used for the
Battery connectors, and the male "pins" are used
for charger, ESC or other Device connectors.
Place the tinned wire into the tinned bullet
connector while heating the joint with the soldering
iron. A cleaned and tinned soldering iron tip will
help provide a clean and secure solder joint. Be
sure to keep excess solder from flowing onto the
outside of the bullet connector. Excess solder on
the outside of the bullet connector will make it
difficult to install the bullet connector in the plastic
connector housing. Use a sharp hobby knife
(and extreme care) or a rotary tool with a grinding
stone or cutting wheel to remove any excess
solder from the outside of the bullet connector.
While the bullet connector is still warm from the
soldering process, insert it into the back of the
appropriate plastic connector housing. Make sure
to verify the polarity before inserting the bullet
connector, as marked on the outside of the plastic
connector housing. Push the bullet connector into
the plastic housing with a 1.5mm hex driver or
small flat blade screw driver and moderate to
strong pressure, with the front of the plastic
connector housing firmly seated on a solid surface.
You will feel a "pop" when the bullet connector is
properly locked into the plastic housing.
