18650 Lithium Battery Holder Case with Wire Leads (4 Slots)

Using raw lithium batteries can be tricky without the right holder. These cases provide a safe, secure way to mount standard 18650 cells and connect them to your circuit. They feature sturdy springs for good contact and come with pre-stripped Red and Black wire leads for instant soldering. Crucially, these holders connect the batteries in Series, meaning the voltage adds up with every slot you add. This allows you to easily build high-voltage power packs for motors or Arduino boards.
