Firstly, should this thread be here or in machining/materials.
I want to hobble together the cheapest, most durable interior, brightest (v6 bin, driven 4 to 700ma cc) task headlamp from scratch (more or less).
The 2s x 18650 holders in past projects are touch and go, with my $5 price limit.
I don't like-hate is a weak word- the long tube. I want a super light side by side cell configuration. Water proofing isn't needed, soft silicone foam is probably best.
My design is just take a sheet of stiff plastic retangle, glue elastic loops to hold two cells in place (side by side) on the rectangle plastic base. A long oval rare earth magnet for one end to join both batteries in parallel. And two round ones for the wired end.
1. can these magnets be soldered together and solders to a wire? Do they conduct electricity?
(I have other questions about other aspects of the design, but one question at a time.)
