Glad to share XTAR 18650 4000mAh, 21700 6000mAh & 26650 6000mAh tests by lui_gough.

Let's check how the testing results of the XTAR VX4 grading function would compare with a proper, temperature-controlled 25-degrees Celsius test at C/5 with the Rohde & Schwarz NGM202.
He also made the cycle life tests on these batteries. For example, "The degradation data for the 21700 6000mAh cells came to a rate of 1.6243mAh/cycle for sample A and 1.6440mAh/cycle for sample B, which is pretty similar. Trend was observed to be linear. As the 6000mAh capacity of these cells allows 1200mAh to be lost at end-of-life, the calculated cycle life would be 738 cycles and 729 cycles respectively, both greater than the claimed 600 cycles, assuming the linear degradation trend holds."
