18650 Battery Holder Case with Wire Leads
Reliable Portable Power Supply for Microcontrollers & Robotics
Power your mobile electronics builds with our heavy-duty 18650 Battery Holder Cases. Designed to hold 3.7V 18650 rechargeable lithium-ion cells in series, these compact enclosures deliver steady DC voltage directly to your projects.
Equipped with color-coded red and black wire leads, these battery packs provide an instant power source for mobile robotics, wireless sensor nodes, smart home prototypes, and portable IoT setups. Connect the pre-stripped leads to motor drivers, step-down (buck) voltage regulators, terminal blocks, or DC barrel jacks to power 3.3V and 5V platforms—including Arduino, ESP32, ESP8266, Raspberry Pi, STM32, and Single-Board Computers (SBCs).
Series-Wired Output: Combines 3.7V 18650 cells in series to provide higher operating voltages for motor drivers, buck converters, and onboard regulators.
Pre-Stripped Color-Coded Leads: Features red (Positive) and black (Negative) wire leads for quick soldering, breadboard insertion, or screw terminal connections.
Impact-Resistant ABS Construction: Durable molded housing with heavy-duty steel spring contacts keeps battery cells firmly in place during movement and vibration.
Essential Workbench Utility: The go-to power solution for mobile robots, solar-recharged IoT stations, and custom field-enclosure projects.
