100 Pcs 18650 Lithium Battery Cell Holder, Battery Storage Box Cell Spacer Bracket Stand Plastic Battery Pack Bracket Cylindrical Cell Battery Stand for DIY Fixed 18650 Battery

Now these are a pain in the ass to put together but once you do they're good to go. Fits the batteroes nice and snug!

Have not used these yet but they look like they will work good for my project. There is not much to review here, the only problem(s) I see is they could break when batteries are installed or not stay in place, but a bit of glue will stop that.

Excellent product. Easy to use and separates the 18650 cells nicely Easy to clip together and sturdy once assembled.

Exactly what I was looking for.

Makes it easy to build a battery pack. They are a little large for the 18650 batteries and do not hold them as tightly as I'd like. Battery packs while you're building them have to be taped or at least rubber banded or they fall apart. The individual pieces hold together well though and can be put together in many different ways which is handy and you can build a lot of different configurations.

The were good holders you just have watch the line up the connections or the next layer won’t fit right

Nice

They're the diameter of 18650 batteries. You clip them together to the size you want, fill with batteries, then put another one on top. There is space in between for nickel strips. Overall, exactly what it says on the tin!
