18650 Battery holder
experiment |
I have been fooling
around with HDPE, High-density polyethylene,
cutting out some 18650 Battery
holders.

Some of the possible shapes that I can cut.
2, 3 and 4 18650 battery shapes can be cut.
I suppose even more than 4 x 18650 shapes
could be cut also. |

Prototype #2
I cut some copper clad boards that fit down
into the ends.
The four battery chambers are joined together
so the circuit board can drop down inside.
The battery terminals get soldered to the
copper board.
The nut that holds it all together is big
enough to grab hold and twist with gloves on |
Side View with a couple 18650's loaded.
You can see the big nut on the end. |

Prototype #2
A shot with the Battery terminals soldered to
the copper boards |
The copper boards snaps down inside the ends.
I didn't need any glue, the fit was snug.
You could use a dab of glue to hold the boards
in place. |

Prototype #1
I tapped 1/4-20 threads into the base.
The threaded Nylon rod in the center is
screwed into the base.
The top piece is drilled smooth so the
threaded rod can pass through the top.
The nylon nut secures the whole rig together
nice and tight.
The battery holder, rod and nut weights 28
grams. :) |

Here's a shot with some 18650's loaded into
