3 x 18650 BLM Cell Box, with Pin, Without Cover

Through-Hole PCB Solder Pin Terminals: Equipped with bottom solder pins designed for direct through-hole mounting onto circuit boards, securing high-voltage power lines for custom PCB designs.

Triple 18650 Cell Series Configuration: Accommodates three 18650 cylindrical lithium-ion batteries in series to deliver a nominal 11.1V power rail (12.6V peak) for motor drivers, high-power robotics, and LED systems.

Coverless Open-Frame Enclosure: Open-top design enables maximum natural heat dissipation and fast, tool-free battery insertion or replacement during testing and prototyping.

High-Tension Spring Contacts: Heavy-duty nickel-plated spring terminals maintain continuous physical contact pressure, preventing power dropouts under structural movement or vibration.

Molded Polarity Markers: Clear positive (+) and negative (-) symbols molded onto the base tray floor guard against reverse battery polarity and downstream circuit damage.

Flame-Retardant ABS Plastic Housing: Crafted from durable, heat-resistant black ABS composite that resists wear, impacts, and high soldering temperatures.

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

Terminal Material: Nickel-plated steel spring contacts with PCB solder pins.

Technical Specifications:

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

Termination Type: Through-hole PCB solder pins.

Color: Matte Black.

Usage Advice: Align and seat all bottom solder pins completely into PCB through-holes before applying solder for proper mechanical stability.

Maintenance: Periodically check contacts and wipe clean with isopropyl alcohol if flux or dust builds up.

Essential Board-Level 12V Power Module: Position as the ideal PCB-mountable battery housing for 11.1V - 12.6V power rails in robotics chassis, drone power hubs, and high-drain DIY projects.

Highlight High Capacity & Direct PCB Pin Mounting: Emphasize the convenience of direct through-hole PCB assembly combined with high 3-cell voltage capacity for demanding electronic builds.
