Excellent for 26650 batteries
I love these things.  I use them for my custom ecigarette mod boxes, and these springs work great for 26650 battery contacts.  They are perfect for snapping right on to bare circuit board, which I use for the battery end supports in my mods.  On the back of these, not shown in the pictures, there is a solder ring which &#34;almost&#34; fits 24 gauge solid copper wire.  By very carefully prying on the solder ring with a small microscrewdriver, I can spread the ring just enough to allow the 24 gauge to slide right in.  Buy some extra springs though if you need to modify them like this, as the solder tab will break off if pried too hard.<br /><br />I get ZERO voltage drop through my circuit when using these, so they're fantastic for unregulated mods.  For 18650's, get the AAA springs instead, as they are narrower.
