Rube Goldberg Tackle Box Cell Cradle

donn_ · Aug 11, 2009

After considerable rummaging through my parts bins, I came up with this parallel charging cradle.

That's a 26650 A123 cell in there, but it will (with spacers) hold anything from CR2 to M cells.

(AW C w/spacer and 17670 with split-tube underneath.)

Now I need to find the appropriate power supply and/or charger to power it.

The batteries shown are for example only aren't they Donn? your not going to charge different cells in parallel are you?
I have an old dead NIMH charger AAA to D that is bigger enough for 18650s and I have often thought I should use it as a cradle for my hobby charger.

Hi Norm,

As I understand it, one can charge different capacity cells, of like chemistry, at the same time as long as it is in parallel.

Is this a misunderstanding?

I'm sure they need to be the same type cell in similar state of discharge, I'll try and find a link.

I'm confused reading both these links.
Reading a bit more looks like your OK as long as you follow the restrictions given in both threads

sorry if I caused you any distress
