2 x 1.5V AA Battery Holder with DC 2.1 Power Jack

The 2 x 3.7V AA Battery Holder is capable of storing two 3.7V batteries, allowing for the creation of a rechargeable battery pack with a voltage of approximately 7.4V. It can be used with NiMH / NiCd cells or alkaline cells to produce a 7.4V battery pack, as the holder places the batteries in series, resulting in six times the voltage of a single AA battery.

The product includes a DC2.1 Power Jack that can be used for Arduino or other DIY projects.
