DIANN 10pcs 18650 Battery Holder Single 1x 3.7V 18650 Battery Holder 18650 Battery Holder with Wires

Good Quality holders. They seem to be made well.

Just the right size just the right time just the right color of wires very very nice price.

Wire size is very small (27g, maybe 28, about 0.014 inch stranded) and pulls loose easily. The battery is held tightly, you'll have to use something to pry it out of the holder, or trim the sides of the holder down some.

Good for my hobby. Fast shipping, good price.

These work, sort-of, for my low-current app, but anything over 1/2 amp the wires are too skinny. There WILL be voltage drop in the wires. Also- ONLY for use with cells with a + button, the contact on button-less batteries is very poor, and thats what I have ☹️

I bought these to replace a couple of alkaline cells with a single 18650 in a few devices. I will need to add a single cell charge/protection circuit to these, but they work fine for what I wanted. The plastic is typical for these low priced battery cells, but these holders have soldered leads, and the 18650 cells fit fine into these holders. For the price, these are a bargain.

These hold the 18650 batteries securely. Cheaply made, but they meet my requirements nicely.

I used these to make some modifications to Nerf blasters because the typical "D" or "C" battery power source is way to expensive to keep a good supply of, especially considering that some of these things can pull upwards of 60 watts of power! They are super low-profile being only a little bit bigger than the batteries themselves and work great at keeping the batteries locked in place.
