Product Overview: 18650 Battery Holder (4-Slot with Wire Leads)
The 4S 18650 Battery Holder is a heavy-duty storage and connection solution designed to hold four 3.7V 18650 lithium-ion cells. At Robo Tech Valley, this specific model is popular for robotics and high-voltage DIY projects because it pre-configures the batteries in Series (4S), providing a nominal output of 14.8V and a full charge output of 16.8V. This holder is built with impact-resistant plastic and features high-tension spring contacts to ensure a secure electrical connection, even in high-vibration environments like mobile robots.
