Hi all, I've been searching all over and can't seem to find out how low to allow batts to discharge before recharging. Obviously, I aim to maximize the life of my batteries. I'm using IMR 18650 30A Orbtronic SX30 Ultra High Drain Hybrids and charging them with a Nitecore i4. Using them in a Sigelei Zmax V5 that will shut down when the voltage gets too low to power it effectively. Does running the batts that far down do any appreciable damage (life-wise) to the batts. At what voltage do those of you using a regulated MOD recharge your batteries?
