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

Through-Hole PCB Solder Pin Terminals: Features heavy-duty bottom solder pins that mount directly through circuit board vias, establishing a solid electrical and mechanical bond for board-level power layouts.

Quad 18650 Cell Series Configuration: Accommodates four 18650 lithium-ion cylindrical batteries in series to supply a high-density 14.8V nominal (16.8V peak) DC power rail for demanding motor drivers, robotics platforms, and high-drain electronics.

Coverless Open-Frame Cradle: Open-top construction maximizes natural convective airflow for cooling while allowing rapid, tool-free battery insertion and swapping during testing and assembly.

High-Tension Spring Contacts: Heavy-duty nickel-plated spring terminals deliver continuous contact pressure, preventing power dropouts under structural motion and mechanical vibration.

Molded Polarity Identification: Clear positive (+) and negative (-) polarity indicators molded on the internal tray base prevent reverse insertion mistakes and downstream component damage.

Flame-Retardant ABS Construction: Built from durable, heat-resistant black ABS plastic designed to withstand soldering temperatures and mechanical impact in industrial and DIY builds.

Body Material: High-grade, flame-retardant ABS composite resin.

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

Technical Specifications:

Cell Support: 4x 18650 Li-ion Cells (Series configuration, 14.8V nominal).

Termination Type: Through-hole PCB solder pins.

Color: Matte Black.

Usage Advice: Ensure all bottom solder pins are aligned and fully seated in PCB through-holes before applying heat and solder for proper mechanical stability.

Maintenance: Periodically check internal spring contacts and clean with isopropyl alcohol to remove flux residue or dust build-up.

Essential Board-Level High-Voltage Power Solution: Position as an ideal PCB-mountable battery housing for 14.8V - 16.8V power rails in heavy-duty robotics, drone power hubs, and portable power management systems.

Highlight High 4-Cell Capacity & Direct PCB Pin Mounting: Emphasize the convenience of direct through-hole PCB assembly combined with high quad-cell voltage density for advanced hardware builds.
