[Video Tutorial] How to solder 2mm bullet connectors for ESCs and brushless motors

When you buy our eMax motors, the wires do not come terminated with connectors. Although we do offer a soldering service, you may want to solder bullet connectors onto them yourself. If that's the case and you're not completely confident then here's the best way to do it.

2mm Bullet Connector Soldering

For our 1806 and 2204 eMax motors we recommend 2mm gold plated bullet connectors. They are quite small and can be tricky to solder if you don't know what you're doing. The best way to do this is to hold the connectors in a piece of wood. This helps to steady the connector and also stops the heat conducting away while soldering.

The video below shows you the process from start to finish:

Don't forget to finish your connectors with appropriately sized heatshrink tubing - we found that 1/8" heatshrink works well for 2mm bullet connectors.

When you're finished your connectors should look a little like this - electrically isolated and aesthetically pleasing:

I hope this has been helpful to you. As I mentioned earlier, we do offer a soldering service with our eMax motors if you'd rather we did this for you. The motors, bullet connectors and heatshrink are available from our shop below:
