    Calibration is critical for this equipment. Since the resistance value is not very precise, the Constant-Current function of the power supply will be used for precise adjustment. After calibration, different resistor values can be used, as well as different voltage values. But do not exceed 3S (15V) or 3A. Also for higher values a heatsink cooling system is used.

    Hello! How to enter the calibration menu in V3.0? Even if I press the three buttons at the same time (+ power on), it won't enter! I have six such cards (all V3.0) and none of them can be accessed.

    why u needed to pump the psu to 3A to read only 2A on the meter?!! the psu is also inline with the circuit i think both psu and ammeter should read the same

    Assume this is the procedure for using different shunt/load resistors. Seems noone wants to talk about the resistor values much. From what i know the value is critical... or calibrating it is! And if its dumping a full 3A into 3R75... 33W or so. I might try 4x 10w 15R myself... planned on doing some 3s packs, might run for days...

    More thinking... Its limited to 1A on 1s assuming nominal of 3.7(5!)v across 3r75... which will only be 3.75w, across two 5w... no issue. So you could get it to 3A at 1s with a 1R load, etc... for 10 or so W. I better actually hook mine up...

    If you have a CC power supply, do you really need the resistors to be in line? Thanks for sharing.

    Yes , always use resistors to protect internal circuit. From CC power supply ajust to 2A to the end of pcb pins.

    @@RcFixer Why, it makes no sense. If setting the power supply to 2A CC, there is NO reason to add resistor.

    Current limiting might not be reliable with a direct short in many power supplies. It's safer to add a resistor.

    Hi bro, I did all the steps but when I finished and checked the voltage, it was exact with the source but not with the battery, there is 5 tenths of a difference, I repeated the process twice and it doesn't matter to me, do you know what I could be doing wrong?
