D Cell x3 to 18650 x2 Serial adapter 7.5v for 5 Cell Maglite Bulb

This allows a 3x D-cell 4.5v series device to use 2x 18650 batteries at 7.5v

DO NOT USE WITH A 4.5V (3 cell) BULB.

It will immediately burn out unless the 18650 batteries are quite low to make 5v.

I found a "4,5,6 Cell" LED kit at a yard sale for cheap but only had a 3 Cell Maglite with too low a voltage output, so FTJIPI. Hotrodded my "little" Maglite.
