DIY 18650 Battery Holder Case Box(10-Pack) Diameter: 18.2mm

You cant ask for more then this; batteries fit stug, plenty of space to solder tabs on, and they snap together. Makes a nice solid pack that can be adapted for whatever your project may be.

I have been using dead laptop batteries for my night light etc. and this holder really works if i want to make a battery pack or keep the 18650 from rolling.

Slow delivery, otherwise as advertised. Work fine for 8650s

My fault not the right size.

not exactly the one size fits most that was advertised.I recommend buying one and seeing if it fits first.

Perfect holders for welding the tabs on 18650 Li-ion cells

This fit together tightly and really make for a nice battery pack.
