About this item

The 18650×2 Battery Holder with Cover and On/Off Switch (with DC Jack) is a robust, plastic-cased solution ideal for compact, battery-powered electronics. It holds two 18650 lithium-ion cells in series to deliver a combined output of 7.4V, suitable for devices requiring moderate power. A sliding cover, secured by a small-head screw, offers excellent protection from dust and mechanical stress, while helping neatly organize the cells. The integrated on/off switch allows convenient power control, and a DC jack is included for easy external power connectivity. Two pre-soldered wire leads (about 12–15cm long, with the last 5mm tinned) support quick and secure connections. Crafted from high-quality plastic, the holder is lightweight (~33–35g) and compact (approximately 90×43×22mm), making it a practical addition to DIY builds, robotics, or portable power projects. Robu.in backs it with a 15-day warranty against manufacturing defects.
