Just got a motor back from repair, and found that they cut the wires coming out of the motor a little short. When installed on my Ion-X, the wires from the motor no longer reach the wires from my controller. Thus, I cannot solder them to eachother. Instead, I'm going to have to splice separate wires between the two (i.e. there will be two solder joints between the motor and speed controller rather than one).

Provided I do a good job soldering, is there any problem with this setup? Are there any reliability issues (or performance issues) with having an extra solder joint?

Any special considerations I must make?

A good solder joint will pass DC current as well as the wire, no problem. If I can, I like to shove the strands of each wire into each other, rather than beside each other, then press the wires together, so no little strands stick out. This provides a better connection and is physically smaller and makes a neater joint when heat shrink wrapped. Joe...
