thiss 18650hr20r cells, very good.
The Samsung 20R is a very close relative of the more popular Samsung 25R. In this experiment, the battery's internal structure was slightly altered to favor maximum discharge current, as the 20R is rated at 22A. In the meantime, the 25R is rated at 20A. As usual, the trade-off between higher discharge, and lower capacity has occurred and the 20R is limited to only 2000mAh. As most discover, 2 amps is not worth giving up 500mAh and the 20R has lost support to the more favored Samsung 18650 25R.
