    How can you set the cutoff voltage for capacity testing? It is not in the manual

    Could I use this to put a solar panel under a load to check its output.

      Yes you can do that...

    Is it possible to explode if I try for example drain 40A while testing a 18650 of only 20A ???

      it is guaranteed.

      @@B.E.H. ah, I see. Dead short test. You would probably need a current shunt and an oscilloscope. The peak would be instantaneous and faster than any multimeter or these testers would be able to register.

      @@BKD70 Hi friend... "Dead short test" is the name for this kind of test we are talking about???
      If I understand, you told me that ONLY USING OSCILOSCOPE I can get the peak current, right???
      I think while we maintain the short, I mean for 2 seconds, we can see the current using the multimeter, just faster, dont think so?

    have you done multiple internal resistance checks to compare it wiht your meter? i don't want to buy a one function IR meter if i can just buy this capactiy 8 in 1 checker.thanks

    Hello friend I buy 1 if that, last night I empty 5 pcs 14v lifepo4 battery pack, works very well, but when I plug it out and thus morning plug it again, device will turn on but when I connect any cell or battery, shows voltage of it but not work volume controls and current not change from zero and also cooling fan not work, do you know what's problem of it?

    maybe voltage drop because of the length of the cable

    • @em0_tion
      @em0_tion 4 ปีที่แล้ว +1

      Nope, this is why he changed that puny cable with the 30cm fat one, no logical reason to expect voltage drop from it. These extremely high 20 Amps would've otherwise made the tiny original cable melt/catch on fire/vaporize ;) You can use this cable voltage drop calculator if you have any doubts or just wanna check for future applications when you wonder what cable you might need ;) www.calculator.net/voltage-drop-calculator.html
