Description
This battery holder was designed to be used in a flashlight, but will work for other projects with a cylindrical housing. The batteries are connected in series, so the pack will output approximately 4.5VDC. Because of their design, the packs themselves can also be connected end to end, creating higher voltages in a longer tube.
The battery holder measures 21.6 mm in diameter and 65mm. The positive end of the battery case has a spring loaded pin which can compress approx. 4mm.
Please Note: Batteries not included.
