What People Say
The bronze pins are a nice touch, they solder perfectly to my custom PCBs without any issues.
Incredible value for the price. I've used these in several power bank builds and they hold the batteries very securely.
Finally, a compact holder that doesn't feel like it's going to snap. Great quality for DIY robotics.
Problem & Solution
Finding a secure, cost-effective way to mount 18650 cells in custom electronics projects is a common headache for makers. Flimsy DIY setups often lead to loose connections, flickering power, or the risk of short circuits, which can ruin hours of hard work or even damage your expensive lithium-ion cells.
This 18650 SMT battery holder solves these issues by providing a professional-grade, rigid housing that locks your cells in place. With its bronze pins designed for stable surface mount soldering, it ensures a consistent electrical connection, giving you peace of mind that your power bank or custom device will function reliably every time you flip the switch.
Who Is It For?
This product is perfect for DIY electronics hobbyists, Arduino and Raspberry Pi enthusiasts, and custom power bank builders. It is an essential component for makers who need a clean, modular way to integrate 3.7V power into their prototypes without messy wiring.
It also appeals to students and engineers working on small-scale robotics or portable lighting projects who require a compact, lightweight, and incredibly affordable battery mounting solution.

- Plastic tabs can be tight on the first insertion
FAQ
These holders are designed for standard flat-top cells; protected cells may be a very tight fit due to their extra length.
Yes, the bronze pins are chosen for their excellent spring tension and conductivity, making them far more durable than standard steel contacts.
No, this is a battery holder component. You will need to add your own BMS and charging module to build a complete power bank.
Because these are SMT (Surface Mount) pins, they are intended for PCB soldering, not breadboard insertion.
Final Verdict
For the price of $1.36, this 18650 SMT battery holder is an absolute steal for any serious maker. It balances affordability with high-quality bronze contact points that you simply don't find in cheaper, generic alternatives. Whether you are building a backup power supply or a portable LED rig, this holder provides the stability and professional aesthetic your project deserves. Highly recommended for the DIY enthusiast who values reliability without breaking the bank.
