New Project Supervisor Here: Line of LiFePo4 Lights

2,7V would be too low here, especially with LIFePO4.

2,5V would be perfect. Not too low, and not too high.

About low VF LEDs, how about we go with Nichia 219Cs triple setup instead ran at 2.8A max and a CC FET driver?

That would make for an absurdly low voltage capable setup.
And with BeCu springs, you’d be getting the best regulation possible.

Well I was basing the 2.7V cutoff on this chart:

(This cuts off at 2.6V … I added +.1V just to be safe.)

Also what does V-subscript-f stand for exactly?
