18650 x 3 Battery holder Case

Triple-Cell Series 11.1V - 12.6V Output: Accommodates three 18650 lithium-ion cells wired in series, providing a 11.1 V nominal (12.6 V peak) power rail for high-drain robotics, LED drivers, and 12V equipment.

Pre-Stripped Color-Coded Lead Wires: Comes pre-wired with 22AWG positive (red) and negative (black) flexible copper leads, enabling fast soldering or breadboard connections without extra assembly.

Enclosed Molded ABS Construction: High-density black ABS plastic housing securely holds three 18650 batteries in place, protecting cells against physical shock, drops, and chassis contact.

High-Tension Stainless Steel Springs: Heavy-duty spring contacts maintain positive battery pressure under vibration, ensuring continuous power delivery without intermittent drops.

Molded Polarity Identification: Clear positive (+) and negative (-) polarity symbols molded into each slot prevent accidental reverse insertion and electrical shorting.

Integrated Mounting Base Holes: Pre-drilled countersunk mounting holes on the base plate allow easy screw mounting to custom enclosures, drone frames, or project boxes.

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

Terminal Material: Nickel-plated stainless steel spring terminals with copper lead wires.

Technical Specifications:

Cell Support: 3x 18650 Li-ion Cells (Series configuration, 11.1V nominal).

Lead Wire: Approx. 15cm color-coded insulated wire.

Color: Matte Black.

Usage Advice: Install three 18650 cells with identical charge levels and capacities to ensure balanced series discharge performance across all slots.

Maintenance: Keep internal spring contacts clean and dry; wipe with isopropyl alcohol if dust or residue accumulates.

Essential Power Source for 12V High-Drain Applications: Position as a top-choice 12V battery solution for mobile robotics platforms, custom power banks, RC vehicles, and portable microcontroller setups.

Highlight High-Capacity 3-Cell Setup & Pre-Wired Leads: Emphasize the convenience of ready-to-use color-coded leads and high power density for projects requiring more voltage than dual-cell holders offer.
