18650 Battery Case Holder, 4 Pcs 4 Slots x 3.7V DIY Battery Storage Box, in Parallel Black Plastic Batteries Case with Pin for 4 x 18650, by Ltvystore

The contacts are fairly Stout and springy which I liked but the little legs look like they were supposed to be mounted on a PCB are awfully small. I used five of them to make a 20 volt pack to run my portable PCP compressor. I also use it for my light bar to make night in to day. 20 of 18650 cells should be over 25 amp hours! Some xt60 connectors, some 12 gauge wire and a big soldering gun ⟵⁠(⁠๑⁠¯⁠◡⁠¯⁠๑⁠)

These battery holders were perfect for my purposes. The only issue I have with them is the + and - signs that are inset into the individual battery slots are misleading and not always accurate depending on how they are used.

flat top 18650 batteries fit great , the contacts are a nice tight fit . Each battery bay is independent so you can wire them for parallel or series Projects. They Definitely handle higher loads than the spring style connectors but they are by no means suited for high output applications They are made of a thin rigid type of plastic which holds its shape well and keeps the batteries connectors nice and tight however if you were too rough with them they can crack All in all they are good value and work well for light duty applications

They came bulk packed in a plastic bag. They were complete and in good condition.I'm going to turn them into a serial/parallel battery back to get 7.4 volts out at twice the capacity. If I have any issues I'll change this review. But so far I'm happy.

The cell holder walls are deep and squared so you have to work a little get the batteries out once they are in. On the plus side, they are very secure once seated. Would recommend for use with LiIon charge module so you don't have to dig the batteries out to recharge them.

Fits my EBL 18650 button top batteries perfectly. It's made of sturdy plastic, no weird smells, and fast shipping. Bought others holders but didnt fit my batteries so im glad these did!

The batteries for very tightly at first which I found as a plus and there is no specific orientation so you can solder and load the batteries how ever you'd like.

the plastic will crack if you jam it in. like the rubber from last spring you found in the glovebox.. if your boys are too long.. grab elec tape and needle nose pliers. wrap the case to prevent the cracking the will almost certainly happen . BUT these will give you satisfaction only after some careful foreplay. create room for the 18650 via squeezing the metal clips at each end of each compartment.

Always very useful, even if batteries are a bit hard to remove. I simply use a small screwdriver and pry out from the negative side to prevent damaging battery shrink wrap.

Very nice product. However, I found the same product on banggood, for about the same price you get 20 battery holders instead of 4. I have ordered those to make sure thet are the same even if the picture look exactly the same.

Excellent product,could not complain working as it should.Would be better if i could by more.Not just the 4 pack

Solid reliable parallel cell holders
