Product Description The 4-Slot 18650 Battery Holder is a heavy-duty, open-frame enclosure designed to house four lithium-ion cells in a series configuration. By combining the voltage of four 3.7V cells, this holder provides a substantial 14.8V to 16.8V output, making it the ideal portable power source for high-torque 12V-15V motors, powerful LED arrays, and advanced robotic platforms. Its robust design and high-tension nickel-plated springs ensure a secure electrical connection, preventing battery displacement even in high-vibration mobile environments.

Key Features

High Voltage Potential: Perfect for 14.8V systems or powering 12V devices via a regulator for maximum efficiency.
Efficient Heat Dissipation: Open-frame design prevents heat buildup during high-current discharge cycles.
Standardized Integration: Features ~15cm color-coded leads for rapid connection to motor drivers or PCBs.
Durable Construction: Built from heat-resistant ABS plastic to withstand industrial and hobbyist use.
Universal Fit: Compatible with all standard flat-top and button-top 18650 lithium-ion cells.

Technical Details

Dimensions: Approx. 78 x 76 x 20 mm
Wire Length: ~150 mm
Wire Gauge: 26 AWG
Spring Material: Nickel-plated steel for superior conductivity
Color: Industrial Black
Weight: Approx. 28g (excluding batteries)

Prototyping and Engineering Tips from Robogears

BMS Requirement: Because this holder connects four cells in series (4S), you must use a 4S BMS (Battery Management System). This protects individual cells from over-charging and over-discharging, ensuring the safety of your high-voltage pack.
Motor Driver Pairing: This holder provides a nominal 14.8V, which is the "sweet spot" for many high-torque DC geared motors. Ensure your motor driver (like the L298N or IBT-2) can handle up to 18V to account for the full-charge peak.
Voltage Regulation for Logic: 14.8V is too high for the VIN pin of most microcontrollers. Use a Step-Down (Buck) Converter to drop the voltage to a stable 5V for your Arduino or ESP32 logic while using the main rail for your actuators.
Mechanical Security: Use M3 screws to fix the holder firmly to your robot's base. For combat robots or high-speed rovers, we recommend adding a Velcro strap over the cells to prevent them from ejecting during sudden impacts.
