Here's a shot of both half's of the 4 x 18650
Battery Holder. The groove running down the back side is the wire channel. |
Start by tapping both half's together with vinyl electrical tape |

Here you can see the groove for the power wire Both half's are tapped together |
Press the battery terminals onto the battery
holder ends. This battery holder is a 3.6 volt parallel battery holder. All four + terminals are on one end All four - terminals are on the other end |

Wind some wire through the terminals to
connect them all together Solder the wire to the terminals. Warning: Solder very quickly and get the soldering iron away from the terminals. You will melt the HDPE plastic if you take too long to solder the joint. I use a 40 watt soldering iron for this because it can solder very quickly |
Here I have split my wire so the
red positive wire
doubles back onto itself. You can slide on some heat shrink tubing now if you want to use it. I am using the Red/Black zip cord shown above for my power wire. You can use what ever type connector you like to use. Just make sure you wire the + and - wires correctly |

Shove your power wire into the wire hole. The tip of the + wire can be seen sticking out of the wire hole. The tip of the - wire also sticks out the hole on the other end See the picture on how I split wire |

Make a hook shape on the + and - wires and
solder them to battery terminal wires. Pushing and pulling the main wire will help you position the + and - wires |

Wrap vinyl electrical tape around the battery
body to cover up the bare wires This also holds the battery holder half's together as one. See the Velcro strap tip below |

Here's a nifty little trick I just figured out
the other day. Take a Velcro strap and tape it down as you are wrapping the battery holder body with tape. I picked up a roll of these 15" long Velcro straps at Lowes. They come in handy for lots of things |
