Nickel-plated steel pins: Strong conductivity + stable contact. Nickel-plated steel spring contacts ensure stable power supply without interruption. It has passed the 48-hour salt spray test, is resistant to oxidation and rust, firmly fixes the battery, and solves the problems of poor conductivity and loose contact. Not bendable. Only for PCB insertion and soldering.
Precise slot position: Compact and fixed without loosening. The precisely processed slot position perfectly fits the 21700 flat-head battery, ensuring no shaking during use. Provide continuous and stable power supply for PCB projects (such as Arduino kits and small electronic devices), solving the pain point of power failure caused by loose batteries.
Safety Installation Guide: Short-circuit Prevention + Easy-to-operate step-by-step safety usage process: Tilt and insert the battery (first the positive terminal), then press the negative terminal to fix it. Disassembly starts with the negative terminal to completely avoid the risk of short circuit. Solve the core pain point of easy short circuits during installation, and even beginners can operate safely.
Safety Warning: Prevent scratches. The steel contact pins are sharp. Be careful during operation to avoid scratches. The built-in safety design strikes a balance between functionality and protection, addressing concerns about injuries from sharp components and providing greater peace of mind during use.
PCB project on-demand adaptation: Each package contains 1 three-slot battery socket, which is sufficient to complete DIY electronic projects or as a backup replacement, solving the core pain point of insufficient accessories in the middle of the project and meeting the batch production needs of electronic enthusiasts
