i dont know that this charger has automatic current selection. But you can adjust the current manually with CH1/CH2 button and cycles through 3 current selection which is 1A/2A/4.1A.
i Received mine, Nice charger look different compared to other black design. This the LCD and the informations on it. Bright LCD with good angle.
Charging 26650 at 4A is hot though as you can see.
I own the tube and i attached it to my car key it is nice that the body is polycarbonate not some alluminium like most AAA light that will eventually scratch the paint.
My last one bought Nitecore EC11 nice little light loves it. I wish Nitecore sell seperare body for AA and 18650 version since all seems to use the same head.
Sorry for the late reply. Yes i use the max lipo gauge to read the voltage as i have them lying around, or you can just use analog input from one of the arduino pin and some voltage devider. The max chip communicates through IIC interface with the arduino. In recent changes i also add current...
Well this is an old thread, i just build a glorified tp4056 charger using a dead 18650 charger as a host.

S**T you even dare doing a white wall testing on that beast lol...
That is a good charger and firmware is always updated and features added per user request.
Here is the official thread at RCGroups created by the manufacturer. Good luck reading 550 pages of it, Happy reading :)

cant make it out clearly but i can guess. It is probably a pass-through board which means the LED is directly driven(no driver in between) by the battery.
