18650 Dummy Batteries, Where do you hide?

Fiddy · Sep 2, 2012

G'day,

Ive been searching for dummy 18650 batteries so i can use single cell drivers on multi-series battery arrangement hosts.

Ive got 14500, 10440 and 16340 sized dummy's but no 18650 sized ones.

Does anyone know where i can find some?

Cheers!

Fiddy.

I make my own out of 80-cent hardware-store variety wooden rods and a length of wire.

Wooden ayy? ive done the makeshift wire approach but want a removable option, if the interwebs fails, i think ill machine some up and heatshrink em..

Why not use two 16340 dummys?

I haven't ever seen one. I've made all my dummy batteries with threaded rod from the hardware store cut to size with a hacksaw and wrapped with shrink wrap tubing. A dremel or grinder is also helpful to bevel one end to make a sort of button top.

Can you just use two CR123 spacers, like these?

Edit: Dang you guys are fast.

i knew that question was coming and i dont have an answer lol

All i can put it down to is, i need to buy a twice as many of the spacers if i buy the 16340 sized ones and just my personal preference.

G'day!

Solarforce sells this flashlight with 3 18650 dummy batteries.

Maybe you could email them and ask if you can just buy the dummies.

thanks hippy hop! ill email some eBay sellers that sell that "gladiator" to see if they wanna sell me the dummy's only

Hey if you cant get them, a plastic white board marker pen has the same diameter as an 18650...you could cut that to size and add a metal rod. I did something similar for a 10440 and a 14500, although they were different sized pens!

No, I mean get a rod just a bit smaller than 18mm wide. Hardware stores sell (usually around 4 foot lengths) various diameter round wood rods. I'm sure you've seen them before.

Cut a ~6.5cm length, run a length of wire from one end to the other. Secure the wire however you see fit. I used brass thumb tacks.

Total cost is about $2 for 18 of them.
