After receipt I charged every Cell fully up to 4.2V separately and installed all of them into a power bank. Then I discharged the power bank at its USB 2A output with a resistor of 5Ohm What could I expect with this batteries at minimum capacity of 2500mAh? 10Ah @ 3,7V or 37Wh or ( ~ 90% max. discharge ) 33Wh or ( ~ 90% converter efficiency ) 30Wh or 6000mAh @ 5V Unfortunately I measured only a capacity of 4230mAh or converted per battery 1760mAh! What would you think about a car with advertised minimum speed of 250km/h that achieves only 176km/h? Bad luck or was it lied?
