2 x 18650 Battery Holder with DC 2.1mm Jack

This battery holder takes two 18650 lithium cells and connects them internally in series for a standard 7.4 V output. It is a simple way to power electronics projects from common 18650 cells, such as those used in laptop battery packs and power banks.

The holder includes a DC 2.1 power jack, making it suitable for connecting to compatible Arduino boards or other devices that accept this barrel-style input. The enclosure uses an ABS shell with a durable spring contact structure.

One 2 x 18650 battery holder with DC2.1 power jack is included. Different batches of DC connectors may have slight differences in appearance, but this does not affect use.
