Step 4Complete the battery pack
Strip your battery wires (if not stripped already. You tested your lites right?), and place the correct size heat shrink sleeve (fits over the N size jack without it's nut and washer) onto the wires.
Make sure that the nut and washer are removed from the jack.
Tin the wires and solder the wires onto the jack.
Slide the sleeve onto the jack as shown.
Shrink the sleeve over the front of the jack slightly, then shrink the sleeve back to front.
Insert the batteries and test your jack to see that you have 12VDC there. If not, why not? Do you have good terminal connections? Did you melt the terminals and it just now showed up? Is the jack soldered correctly?
IF YOUR BATTERY PACK GETS HOT, REMOVE THE BATTERIES, YOU HAVE A SHORT CIRCUIT. THIS SHORT MUST BE REMOVED BEFORE CONTINUING
If the battery pack measures OK (12VDC), Leave the batteries installed.
Cut a piece of 4" Shrink Sleeve as shown. (Approx. 1/2 " or 13mm over on each end)
Insert the battery pack and shrink the sleeve as shown.
Shrink one end of the pack slightly as shown.
Then shrink the other end, and continue to shrink the sleeve over the entire pack.
Our last photo shows the completed 12VDC battery pack. Congratulations, You've done it. You'll be able to power your lights.
You can also make these packs to power other items on your bike. With this pack you'll get about 2 hrs of light. To increase the run time, you could increase the battery count by 2 or 3 but then you'd need a different charger and I don't think the additional run time gained would be that much.
You'd be better off building another pack and creating a "Y" harness to parallel the two packs together (Like jump starting a car, + to + - to -). Using two of these packs in a parallel configuration, would give close to double the run time.
