The 3A ran down to 1.58v, which is a disaster for the cell.
Lithium nickel chemistry, LiNiMnCoO2 (INR), like lithium manganese, LiMn (IMR) and other hybrid chems, can tolerate over discharge to some extent
This costs twice as much as F12 or H10 and has a 1A max continuous discharge current rating. If protection is desired, I'd steer towards KeepPower's P1450C2, costs less, but no built in charger, but it least it has a 4A rating. That is, of course, if it fits.the Protected Lumintop 14500 w built in USB charging, solves the lack of reliable LVP in the SC53 series
Though it definitely has been for the majority of the time liion has been available by a wide margin, I'm not sure it is the most common anymore today. Seems to have largely been superseded by hybrid chemistries such as NCR and especially INR, while IMR availability hasn't seemed to have changed either way. Just my personal impression, ymmv.The oldest and most common lithium-ion battery chemistry is know as ICR - Lithium Cobalt Oxide (LiCoO2).
Hard to tell exactly what the runtime is on either. Surely, F12 has more runtime, but just looking at Test 2 and Test 3, both cells dropped down to cell-damaging voltages. I don't know how you'd calculate from Test 2 what the runtime would have been when the cell was at 3.6V, when the test should have ended (which is not Lips' fault— the light lacks LVP), but Test 3 ended at 0.84V, which is much closer to 0.9V than, in Test 2, 1.58V is to 3.6V, but it suggests that F12 runtime is probably not twice the runtime of Eneloop Pro.The F12 looks amazing. Looks like double the runtime of the best nimh.
Yes, if you get in the habit of checking battery voltage, and recharge any time it goes below 3.7V.do you think we could use Li-ions in these newer gen zebralights safely?
If you only use it on high 1 and recharge when it drops to medium, that seems like it would work, right? I'd be using their latest headlamp.Yes, if you get in the habit of checking battery voltage, and recharge any time it goes below 3.7V.
Dont allow the battery to drain below 2.7V. Your Brain is the LVP.
Dont fall asleep w the light on at a high enough output to drain the battery overnight.. ;-)

Yup. I have a Fenix hm65r-t which is great, but heavy. I like the lightweight Zebra light h52. My night runs are rarely longer than 1 hour.I dont use maximum output on my lights.. I try to choose lights that are bright enough on Medium, which is more sustainable than maximum, and lasts much longer..
imo, it is not practical to plan on using H1 as a constant output.
In all cases, when using LiIon, checking battery voltage is essential, so you know when to recharge.
Have you considered one of the 18650 headlamps instead? They have LVP, they have 3x higher output on Medium, and the battery capacity is 3x greater than the little AA models..
