My test set up here is;
4 Headway 38120 cells in series with no BMS. but the batteries are balance charged beforehand.
now, after hooking it up, the battery bar shows empty. (yes, I was able to go in the hidden menu and calibrate the voltage according to the battery volt output over the multimeter)
they are fully charged and should show the full battery as 100% or close to 100% instead of 00% like in the image.
on top of that, I don't know how to reset AH?WH?time etc.
this thing, as usual, has no manual or at least a link to go to.
