4 x 18650 Battery Holder Box Case

Quad-Cell Series Configuration (14.8V - 16.8V Output): Holds four 18650 lithium-ion batteries in series to supply a powerful 14.8V nominal (16.8V peak) DC power rail for high-drain robotics, power tools, and high-voltage DIY circuits.

Pre-Stripped Color-Coded Lead Wires: Pre-wired with flexible red (positive) and black (negative) insulated copper leads for immediate soldering onto circuit boards or direct connection to screw terminals.

Rugged ABS Plastic Shell: Heavy-duty black ABS plastic housing securely holds all four cells, protecting batteries against mechanical shock, drops, and accidental shorting against metal chassis walls.

High-Tension Coil Spring Contacts: Nickel-plated steel spring terminals deliver firm, low-resistance contact pressure, preventing power dropouts under heavy structural movement or vibration.

Molded Polarity Identification: Base tray floor features clearly molded positive (+) and negative (-) orientation symbols for each slot to prevent reverse polarity battery placement.

Integrated Base Mounting Holes: Equipped with pre-drilled countersunk holes on the bottom plate for clean, secure screw attachment inside project enclosures or robot chassis frames.

Body Material: High-impact, flame-retardant ABS composite plastic.

Terminal & Lead Wire Material: Nickel-plated steel spring contacts with color-coded copper lead wires.
