11.1V 3 x 18650 Battery Holder Case Box with Leads

Pros: Most important pro is they DO fit protected cells. I have tried these with sku:20392 no problem.
There are holes to mount this holder with screws.
Comes with wires already attached.
Its cheap and does its job well

Cons: Attached wires could be a little thicker.
Outer two batteries can be difficult to remove.

Other: If you need to make a 3S 18650 battery pack then look no further.

Pros: I think it's cheap, and holds perfectly the battery and it is quite strong. It works for prottected and unprotected batteries.

Cons: The cables are a little thin. When you try to pull out the batteries it's quite hard. It can be simple improved if you attach a ribbon under each battery and fix it to the holder case.

Other: The soldering point at both positive and negative pole with the wires are little weak. It can be easy improved.

Pros: Batteries fit well, good quality item have charged protected and unprotected batteies without issue. The screw holes make mounting to any surface easy.

Cons: Wires are a bit thin. The winglets on the two outer cells could be a bit smaller to assist in removing the batteries easier.

Other: Have no problems with this item it works as discribed.
