18650 Battery Holder with Leads – Instant, Solder-Free Power for Your DIY Projects
Working on an Arduino project, an ESP32 module, or an LED circuit and need a reliable power source? These holders come pre-wired and ready for immediate use. Simply insert your battery and connect the leads. This pack includes 5 x 18650 battery holders, each featuring 130 mm red/black leads and a durable, impact-resistant polypropylene (PP) body.
Note: 18650 batteries are NOT included. Each holder accommodates a single battery with a length between 65 and 68 mm.
Why choose this set? (Key Advantages):
- 5-Pack Value — Keep spares on hand for multiple projects without needing to reorder.
- Pre-wired 130 mm leads — Clearly colour-coded red (+) and black (–) for direct, solder-free connection.
- Supports protected cells — Compatible with batteries between 65–68 mm, including those with integrated PCB protection circuits.
- Durable Polypropylene (PP) construction — Resists mechanical shock and deformation, ensuring longevity through repeated use.
- Integrated mounting hole — Easily secure the holder to any chassis, panel, or prototype board using a screw.
- Modular design — Easily connect multiple holders in series to achieve higher voltages (e.g., 7.4V for two, 11.1V for three, 18.5V for five).
Performance and Specifications
The metal contacts within the holder ensure low contact resistance and stable power transfer throughout the battery’s lifespan. The compact 76 × 21 × 20 mm frame integrates seamlessly into 3D-printed enclosures or breadboard prototypes. The 130 mm leads provide ample length for most compact builds and can be easily extended via soldering if your specific project requires it.

Frequently Asked Questions
Are 18650 batteries included in the pack?
No. The package contains only the 5 battery holders. Batteries must be purchased separately.
Does it work with protected (button-top) 18650 batteries?
Yes. The holder accommodates batteries between 65 and 68 mm, making it compatible with both standard flat-top cells and those with integrated protection circuits.
Can I connect multiple holders in series for higher voltage?
Yes. Two holders in series provide 7.4V, three provide 11.1V, four provide 14.8V, and five provide 18.5V. Please ensure your circuit is designed to handle the resulting voltage before connecting.
Is this compatible with Arduino or ESP32/ESP8266?
Yes, this is one of the most common applications. You can connect the holder via a BMS or TP4056 charging module to power your board directly without any additional modifications.
