This is a new brand of batteries, this test is a high current 18650 cell with fairly high capacity.










The matching between the cells is not perfect and they cannot deliver 30A. They do hold their capacity, even at 20A load.















Conclusion

These cells are acceptable, but they do not live up to the 30A rating, they work better at 10A to 15A.
