HiLetgo 10pcs 18650 Battery Clip 18650 Battery Holder 18650 Batteries Case for 18650 Battery with Connect Lead

I am using these battery holders for a radio communications project. I liked that they were exactly as advertised, and they showed up earlier than expected. Amazon must have stocked them at a nearby Fulfillment Center, or something. They showed up on the day after ordering. Hilego products are usually serviceable, well enough made that they work reliably. You can't say that for everything from China. The design is just fine for button top 18650 batteries (which is the advertised spec), but it could have worked for both flat top and button top if the positive electrode had just been a little higher. As it is, I'll have to put a little screw into the positive side to make contact on my flat top batteries. Like I said, Hilego makes it just good enough and plenty cheap enough. How bad is that really.

I used one of these to add an additional 18650 battery in parallel to a solar lantern. It now stays on all night as intended. Not sure why other reviewers had such trouble inserting and removing a battery, they work perfectly. The wires are small, but plenty big enough to power anything under 4 volts.

This is an inexpensive product. The wires are a bit thin for my preference but they do work. There are 2 different versions of the battery that this is for (one is slightly longer) and they both will fit.

They hold the battery quite well, make excellent contact. Would be wonderful for an application where a battery is installed, and left in place for a long period of time. I am using them in a charging application where I charge the battery, then move it. Very difficult to remove the battery, I have broken 3 so far.

I needed way to mount these 18650 batteries to diy robot. I was pleased that even the flat top versions worked too after you settled them in place. I used small screws to mount holder to device frame. The holder wraps about battery abit thus I feel safe battery not fall out under normal use.

They work fine as far as what they were intended to do (charge batteries). However, they are a bear to get the batteries back out of. You have to bend the end away from the battery with force and then pry the battery out. It's a three handed operation. The plastic wraps much farthur around the battery than necessary unless you need them for a 10G application.

Cheap 18650 cases, they don't work out of the box however! KEEP THAT IN MIND!! I had to solder some ball points onto the positive battery end's connector, and from there it worked. On a get what you paid for basis? You truly do get bad quality in exchange for cheap product. If you aren't tech-savy, I would personally avoid this product, however, if you're intuitive and install a RIBBON under the battery (for battery removal), this unit works OKAY. Also, don't expect HIGH CURRENT out of these terminals, they use flimsy wiring and even flimsier connectors.

These did the job, but I just have a couple of minor grievances. The first is that it only has a single mounting hole, right in the middle, so it isn't very sturdy when mounted. It kept pivoting on the screw, so I drilled a couple more holes just so it wouldn't move. The other is that, when you first put the battery in, the spring isn't actually strong enough to push the battery against the other contact on its own. It took me a minute to figure out why I wasn't getting power until I realized I had to manually help the spring a little. The battery stays in place quite well once I do though. I have these mounted to the bottom of my roller skates (powering LEDs) and I have no issues with the battery losing contact once I position it correctly.

Look ok dint use it yet

Good quality

Für meine Zwecke im Bereich Modellbau sehr gut einzusetzen. Die Akkus gehen etwas stramm rein, aber besser als wenn sie im Halter klappern würden.

Perfecto `para mis montajes.Todo bien

Slots per batterie 18650 perfetti. Acquistati per vari progetti di elettronica si sono rivelati davvero utili. Nella confezione ce ne sono dieci (ad un buon prezzo) e credo che mi basteranno per un po’. Per ora ne ho utilizzati due per ricaricare due batterie e funzionano perfettamente. Le dimensioni sono giuste, anche se forse sono leggermente stretti e questo rende un po’ difficile la rimozione della batteria (dipende un po’ anche dalla batteria) ma comunque la cosa non ne compromette l’utilizzo. Sono molto semplici e svolgono bene il loro lavoro. Al centro del supporto c’è un foro per mettere una vite e montare lo slot su un pannello. L’ho trovata una cosa abbastanza comoda, anche se probabilmente non li utilizzerò in questo modo. I cavi sono un po’ sottili, ma per me vanno più che bene. Inoltre, è possibile passarli dai fori laterali oppure da altri due fori che si trovano sulla base. (arrivano nei fori laterali, ma non è troppo difficile spostarli. Ci vuole un po’ di delicatezza per evitare di rompere il contatto). Sono molto contento dell’acquisto, ne avevo bisogno e ho trovato questi di buona qualità e ad un buon prezzo. Credo di poterne consigliare l'acquisto
