Hi stawel

I have calibrate my charger Voltage and Current (Charge and discharge) Vin too, No problem with the calibration I read and adjust the voltage and current correctly I have create Lipo and L435 battery's according my battery's type and characteristic

but when I start charge or charge+balance, the battery not charge even after several hours. the fan is turn on when I enter in charge or charge+balance I think is normal

the screen of my charger after several hours charging one battery LIHV 2S 4,35V 650mAh I precise that the battery is not full discharged and the 87% is the actual charge in the battery when I start the process. for details "10,4V" blinking continually.

thanks

I have investigate and it's appeared that the charger Vout reading is wrong I read with my voltmeter 8,34V but the charger measure 10.4V that blocking the charge launching but I can't calibrate Vout in the Calibration menu
