Bougth it from AE
Far less cheap than King 4000, but with discounts I managed to get it for smaller price than NKON’s Keeppower 26650 7000mAh (and with free shipping).
I’ve also bought a Lii-70S a while back from AE. Normally I don’t buy 26650, since I have only a couple of lights that use that size and I prefer to run 21700’s (with an adapter) in them.
Because I was curious about this cell (and it’s actual capacity) and I could stack a couple of coupons to get the price down to € 5,73 (incl. shipping), I’ve ordered a single one.
I haven’t had time to do capacity/discharge checks, but good to see your test results, thanks!
LiitoKala is a bit confusing on their website, since they basicly list a ‘voltage cut off’ of both 2,5V and 2,75V for the Lii-70S. Taking the 2,75V termination voltage as being the ‘correct one’, your result at 2,8V is pretty close to its rated capacity. There is a good chance that with a lower discharge current (0.2C/1,4A), it should pretty much hit it’s listed capacity at 2,75/2,8V.
So yeah, it appears to be pretty decent in that way!
By the way: I did test/measure, my cells ACIR and it came pretty close to what you measured on yours, with mine being 17,98 mOhm. Still within LiitoKala’s specs of ‘<18 mOhm’, but pretty close to the “max ACIR” it should stay within.
