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

Through-Hole PCB Solder Pin Terminals: Heavy-duty bottom solder pins extend directly through circuit board vias, providing a rigid structural and electrical connection for 7.4V board-level designs.

Dual 18650 Cell Series Configuration: Accommodates two 18650 lithium-ion cylindrical batteries in series to supply 7.4V nominal power directly to microcontrollers, motor drivers, and IoT nodes.

Coverless Open-Frame Enclosure: Open-top cradle allows passive airflow cooling and instant, tool-free battery access for quick cell swaps during testing or routine maintenance.

High-Tension Spring Contacts: Durable nickel-plated spring terminals maintain strong contact pressure against battery terminals, preventing intermittent power dropouts under movement.

Molded Polarity Identification: Clear positive (+) and negative (-) symbols embossed on the interior floor prevent reverse insertion errors and short-circuit damage.

Durable Flame-Retardant ABS Construction: Built from robust black ABS plastic that resists thermal degradation and impacts in demanding industrial or hobbyist builds.

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

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

Technical Specifications:

Cell Support: 2x 18650 Li-ion Cells (Series configuration, 7.4V nominal).

Termination Type: Through-hole PCB solder pins.
