Evaluation of the data:
the 2nd test is pictured in full length as timelapse in this youtube. compared to the 1st test, it shows that the charger has individually consistent slots, the 3rd test (i could upload the proof video too!) shows that the slots are not consistent across the slots. it means that you will get reproducible and consistent mAh-results, as long as you charge a particular cell always in the same effing slot. in other words, data obtained from cell1 tests in CH1 cannot be used together ("cannot be mixed"), e.g. for serious data interpretation, with data obtained from cell1 tests in CH2 or any other slot.

Opus BT-C3100 .. lots of commentary on the internet negative or average on this model charger so it's a problem who's telling the truth

wow man..what can you all do with this awesome charger?Can you also test "the true" capacity (mAh) of 18650 battery's?

Man, this charger is not a precision laboratory device. The videos you post in order to show that it is inaccurate are meaningless in that sense. This is usually a charger for home use with advanced features. For scientific analysis of batteries, completely different devices are used. Compared to lab devices, the SkyRC MC3000 will seem very inaccurate and incomplete. If you are angry that you bought it, just sell it :)
