Can an MC-E M bin wired in series (roughly equivalent to 4 Q5's in series) be run using the Blue Shark and 1 Li-Ion cell (provided the input current is kept within reason)? Most of this thread is about the green Shark, and the input current for that should be limited to ~2A, but what is a good upper limit for the input current on the Blue Shark?
Edit: Vf for led string would be 4*3.4=13.6 at 700mA, so output power would be 9.52W, guessing 80% efficiency gives 11.9W pulled from the batteries, so an input current at 3V of damn near 4A. On the page at the Shoppe it says not to exceed 4A, but I get the feeling that this is cutting it a little close.
For 600mA Vf is ~3.35, so we get about 10W from the battery again assuming 80% efficient, so ~3.3A. Is this bearable?
The crux of it is how much further can the Blue Shark be pushed vs. the green Shark?
