I would would not use those batteries. Here are the test results: "In my opinion, this is a 15A+ continuous discharge current (CDR) cell with capacity lower than its rating. I recommend not using it above 20A as it runs at a very high temperature at those current levels. At its 40A continuous rating the voltage instantly plummets and the cell quickly gets very, very hot. I have included a 40A pulsed discharge (its rating) but I haven't set pass/fail standards for pulse testing yet." https://www.e-cigarette-forum.com/forum/threads/brillipower-40a-3100mah-18650-bench-test-results-only-a-15a-3000mah-battery.702075/#post-16538400
