It will cause an imediate increase in temperature from overgearing. LOL.

Tell me your setup you are currently running Serum, the highest voltage system you have right now thats ready to run. Tell me your current gearing, I will tell you the gearing to run and run one pack through it. If you are correct, everything will be fine and you will get a thermal. This will be an excellent test, please get video as well. This will end all question.
