26650 wf139 cradle

[alpg88]

decided to make a cradle to charge 26650 in my wf139, charging one by one takes long, now i can double the time.
materials
2x 1c radio shack battery holder
perf board from radio shack
clothes hanger, cut it up in little pieces, surface of it covered with some soft stuff, something like you would find lined inside jewelry box.
1\2 screws

used hot glue gun to attach things, and soldered screws to wires.

everything is pretty simple, thou looks ugly.

fits into any wf139, no alterations to the charger needed.

Nice work! I use leads with charging magnets for mine, but this looks like a nice alternative as well.

I assembled this 5xIMR26500 parallel charging cradle for use with a hobby charger. It would be a simple matter to cut the Bulgin C cell holders in half and space the halves farther apart to accommodate longer 26650 cells. Wire is 12 ga Deans noodle wire. I also built a similar setup to charge 3x18650, using a Luminous DIY cradle wired in parallel (didn't take a photo -- sorry).

For the WF-139, I've made simple AA-length plastic spacers with brass nuts and screws on each end for the electrical contacts. The wire in this case is just some inexpensive 18 ga I had. Connectors are AMP/Tyco crimp-on ring terminals. The AA sized spacers allow me to use the same cradles in my AA NiMH charger to charge larger cells (not the best way to charge something like an Accupower C cell, but sometimes a AA charger is all you have).
