Note: displayed current value is function of voltage drop and sense resistor values, which are implemented on the microcontroller unit's software. Bear this in mind for sense resistor mods to change current output, as the displayed current values won't change unless the sense resistor variable value is poked in the software.
If, for example, you 4x the sense resistor value (nice for small cells like 10440s) you need to divide by 4 the displayed current value. No big deal though.
Pete7874, I've bought more Lii-100s from GearBest than I personally need (like a lot of you), but only my first unit looked ”vintage”. The ziplock plastic bag was even removed from the package in the last unit I received (still another one :-D to go).
Cheers ^:)
P.S.: $0.99? LoL! I've got a couple $1.99 sales maybe. Now that you say this, could it be that these $0.99 units are new old stock they are getting rid of?
Mine look like this: https://www.gearbest.com/chargers/pp_272183.html
The 4 percentages on the left is like the shape of a battery. Mine were purchased November 15th last year. $0.99 was related to singles day I guess.
