Pros: Fits two 18650-size LiIon cells. This is not standard AA but the larger size.
Cons: Wires are thin, will not handle too much current. No protection (fuse, resistor) Other thoughts: if u have some cells sitting unused from e.g. an old laptop, this product could be used to make a cheap flashlight. Read more
according to the expectations, both manufacturing materials as the presentation have covered perfectly with the requirements for the project I'm doing, so later will realize new purchases of similar items if still keeping the qualities that have provided me with the adjusted prices that offer the same I have nothing against I will continue buying products ...

- good holder
- Quality is not bad
- not much more to say - very tight for protected batteries
- it does hold the batteries well, but maybe too well, kinda difficult to take them out
- the wires are a little thin - it will be good if it can be configured as parallel instead of series thru some soldering
- instead of giving some thin wire, maybe better ... Read more
It is tight enough to hold the batteries securely even on a bike. The length is enough to accomodate both plain 18650 batteries and the batteries with overcharge and undercharge protection electronics, which are a bit longer than 65mm. The wires are not thick enough for high-current applications, such as switched power regulators for LEDs. I have replaced ... Read more
Can be used in older 7.2 V rechargable electric tools and is small enouch to replace the NiCd or Ni MH 7.2v batterypack, the reason to buy them.
They are small enough to builld them IN the batterypack but recharge is a bit more difficult or a balancer is needed.
Two big advantages you will get, the batteries will remain recharged after even a year or ... Read more

Count 4.1Vx2 when fully loaded basic batteries. No problems to say for it is a rigid holder. Love these holder really good quality. Spring have good tension ... Read more
This battery holder is functioning as it supposed to. I ordered four pieces of it, so I can increase voltage connecting more batteries for my needs. The metal prongs are made from good quality metal,its a shiny metal and it looks like it will last long. I think that it doesn't rust easily. This battery holder has very good contacts. It fits 18650 batteries ... Read more
This is a really good battery holder case box. I got it to hold two of my 18650 batteries for a DIY project to power a Raspberry Pi. Works just fine. I did try to put in some of my longer protected 18650 batteries (Panasonic NCR18650B) but they did not fit as they were too long. The TrustFire protected 18650 batteries fit just fine though. Would have ... Read more
