XT to wires

Part summary:

  • 12 AWG, red, 100mm
  • 12 AWG, blk. 100mm
  • 14 AWG, red, 300mm
  • 14 AWG, blk, 300mm
  • 20 AWG, red, 200mm
  • 20 AWG, blk, 200mm
  • 18 AWG, red, 400mm
  • 18 AWG, blk, 400mm
  • XT90 connector
  • XT60 connector, qty 2 (or 1 male, 2 female)
  • XT30 connector, qty 6 (or 6 female)
  • heat shrink 3/16", 140mm (can do 70mm red and 70mm black)
  • heat shrink 3/32", 180mm (can do 90mm red and 90mm black)

General instructions for each line in the table below:

  • Cut a length of red cable and a length of black cable.
  • Strip a few mm of insulation from ONE end of each wire. The other end will be stripped at a later step.
  • Prior to soldering, connect the female and male connectors together in order to prevent deformation. Put tape over the end you aren't soldering to avoid soldering the wrong end.
  • Solder the stripped end of the red cable to the + side of the connector (and solder black to -).
  • cut 2 pieces of heat shrink. One at time, slide a piece over the wire where it was soldered. Slide it into the connector. You can gently touch around one end of it (the end closest to the XT connector) with a soldering iron to slightly pre-shrink that end. Then it can slide into the end of the XT connector for a better seal. Then use a heat gun to shrink the entire tube.
  • Label the connector (per the table) for future reference.

Here are two slightly different approaches for soldering XT connectors: If the wire does not really fit into the holes and if the wire easily fits into the holes.

Suggestion: After this task is complete, immediately continue with the power loom nodes.
