Calm Consistency
Honestly, I rarely drain past 3.8. I very much enjoy the instant heatup of the higher charged batteries. I'll never drop below 3.6 unless I'm stranded without a battery.Bah don't sweat it too much for the cells, the HE2/HE4/25R/VCT4 can be depleted down to 2.5V. Not that I recommend doing that often. But I think that in order to go that low you would notice that you need a very long preheat time and that's a tell-tale that you need to stop ASAP.
2.5 seems almost impossible to hit, and I'm pretty sure a member killed their battery after dropping it down past 3.4. May be wrong, or coincidental, but that's what I gathered.
