What did you expect? You put twice the voltage to the 2.4 Ω cart as it's capable of taking! The Omicron batteries come off the charger at 4.2V that's the maximum you should use with a 2.4 Ω cartridge.So far I fried a 2.4ohm at 7.4v and a 1.5 at 3.7ohm
The 1.5 Ω cart can be used at the same voltages but with very short button presses! I always told my friends 2 second pulses but you can go a little bit longer. With the Core you can dial down the voltage much lower so you could do longer presses on the 1.5 Ω cart!
If you have an HVD top then you can run above 4.2 V. You could get a 5 Ω cart and run at 7.4V! Again - button tapping not holding with those high powered setups.
