Holder with tabs for 4 x 18650 cells in parallel 3.6V + 8 cm wires

Holder with tabs for 4 x 18650 cells in parallel 3.6V

Holder for 4 x 18650 Li-ion cells wired in parallel is an ideal solution for anyone who needs low-voltage 3.6V power. Made from high-quality rigid plastic, it offers durability and safe use. Thanks to sturdy metal tabs, the cells are held securely, and installation and removal are quick and hassle-free. The holder has 22AWG leads 8 cm long for convenient connection to devices. Compact dimensions of 78 mm x 79 mm x 21 mm make it suitable for many applications while remaining robust and functional. It works well as power for DIY projects, including Arduino, Raspberry Pi, ESP8266, and ESP32.

Key technical specifications

• Cell slots: 4 pcs (18650 Li-ion)
• Configuration: parallel (3.6V)
• Material: high-quality rigid plastic
• Contacts: sturdy mounting tabs for reliable cell retention
• Leads: 22AWG, length 8 cm
• Dimensions: 78 mm (L) x 79 mm (W) x 21 mm (H)

Example applications

1. Powering DIY microcontroller projects - the holder can supply microcontroller-based projects such as Arduino, Raspberry Pi, ESP8266, or ESP32. With low voltage (3.6V) and high Li-ion capacity, it suits devices that need stable energy over longer periods.
2. Portable power for low-voltage devices - the holder can serve as a portable power source for low-voltage gear such as small fans, LED flashlights, or other electronic accessories. 18650 capacity allows longer runtime between charges.
3. Powering measurement systems and sensors in field projects - thanks to compact size and solid construction, it can power measurement setups (e.g. temperature, humidity, or motion sensors) that must run autonomously and portably, such as environmental monitoring projects.
4. Powering robotics and RC models - safe, efficient power for small educational robots and mobile control systems.
5. IoT modules and smart home systems - part of power and backup systems for wireless sensors and communication modules.

Benefits

• Higher effective capacity - parallel connection of four cells adds their capacities for much longer runtime between charges.
• Fast, convenient assembly - factory-soldered 22AWG leads, 8 cm long, speed up wiring into the target circuit.
• Safety and stability - solid contact tabs keep cells secure even in mobile and portable devices.
• Durable, resilient build - high-quality rigid plastic helps protect cells from mechanical damage.
• Compact footprint - flat design eases integration into enclosures with limited space.

This holder is a versatile choice for projects that need stable, efficient power at low voltage.
