Hello The V40 clearly distinguishes between NiMh batteries and does not take voltage from the air, without going into the types because I do not remember, I had end voltages of 1.43V, 1.46V, 1.50V 1.51V, 1.55V. As for the internal resistance, I did not try in the test mode, in the charging mode, it probably takes 45m? rigidly. I will run the full test and see what it shows after the test best regards
Mi Ni-Mh of various brands loads up to 1.52 as I remember correctly. From what I read on the forum swiatelka.pl, the Litokali charger appeared in at least 2 versions - an older one and a newer one, improved. There are photos of the middle of both on the forum.
In the charger a lot depends on the MCU and its fw - the factory does not have to pat for all the same version. I do not know if these chargers are identical or not, but even the common PCB does not prejudge this.
As I checked, the prices of both are almost identical.
