ALWAYS be very careful when soldering battery wires!
A short must be avoided, so only handle one wire at a time, and only when the first wire is properly insulated again then start working on the second wire.
The female plug is used for the battery, male plug is used for the speed controller. Plus and Minus is indicated on the back of the connector. The thick part of the connector is the positive plug.
Tools required:
- Solder iron, 40W or more. Wet sponge for cleaning the tip
- Rosin core solder (standard electronic solder)
- Heatgun for the heat shrink tube
- Sharp knife for cutting wire insulation
- “Third hand” for holding the wire and connector
- Deans connector and heat shrink tubing
Cut the wire insulation with a sharp knife, rolling the wire on the table as you carefully cut through the insulation. The insulation should be cut 5mm from the end of the wire.
Tin the red wire, this will usually take 5-10 seconds to get the heat and the tin to spread to the whole wire. REMEMBER the heat shrink tubing before soldering on the Deans connector.
Place the Deans connector in the grip, and tin the positive connector pin. This usually takes 1-3 seconds. As the connector heats up, the color of the plastic tends to change. Do not worry about this, it is perfectly normal. The Deans plug will revert to it’s original color as it cools off.
Place the wire on the pin and apply heat. As everything is pretinned, the heat will spread fast and the tin will float nicely on both the wire and the pin.
Remove the solder iron, and wait a few seconds for the solder joint to cool.Thin wires can normally be held by hand, but thicker wires must be held by the grip of the third hand, as the wire gets too hot to hold by hand.
Let the solder joint cool completely before sliding the heat shrink tubing in place, otherwise the heat shrink will activate before it is completely in place. Use the heat gun to shrink the heat shrink tubing.
Repeat the process with the black wire…
…. and voila, you are done in no time!
Please note that it is important that you work with the red wire (positive) first on the Deans connector. It can be difficult to solder on the positive wire without touching the negative if soldered on first, and thereby creating an unwanted (trust us!) short.
