I got a Liitokala Lii-600 as my first charger with an lcd. I went about testing my house full of loops and laddas.
In testing mode it charges at 250 and discharges at 500. So generally takes 8 to 10 hours to test.
Tested a few and got 1200 - 1900 for the loops. Some of the low ones I tried to put into the repair mode.
What I found
* after a repair, which took several days the number was lower than the initial test
* running another test, but the numbers were vastly different again
* seems like the second and third slot were consistently high and the first and 4th slot were consistently low
specially the exact same battery tested came anywhere from 1200-1600.
I'm not sure what to expect but I thought it would be something a little bit more consistent?
Clearly the repair did not achieve anything.
Have you seen the same?
Are you suggesting that a $20 charger off AliExpress isn't an accurate piece of measuring equipment? I don't believe it.
