Electrically, that should be fine. Economically is another matter... ;-) You might want to check what voltage you Li-Ion battery is. Since there's usually margin on the 15V DC input so that you can run it off a simple car converter circuit that may be putting out 15V when the car is running but only 12V when the engine is off, you may be able to get by with, say, only 8 D cells. I'd try (at home) running off fewer D cells and see if that works for you... Gary
