Keystone 18650 Li-ion Battery holder. This version also has the polarity markings ( + | - ) and two leaf springs, perfect if you want to use flat top or unprotected cells (which are a bit shorter than a protected button top). It has large solder tabs that I typically remove before securing in a supported chassis. Its as easy as using your pliers to bend the tabs back and forth, for a clean break and then removing the posts on the bottom with a pair of flush cutters or an exacto blade. These take solder very well!
