3*18650 batteries in series, boost driver for both channels

That's interesting. 3S batteries and 4S emitters?

4S wouldn't be enough for low modes, 2.5V×4=10V, while 3S cell would be 12.8V fully charged, so with boost the only viable configuration would be 8S. I wonder if it's an error since he said it was a dual buck driver on BLF.

Buck would make the most sense.
