So, did I get the wrong Dual Coil Cartomizers? I don't want to mess up my Ego. !
Don't sweat it. A lot of people think that the mofsets that regulate the ego batts and their switches are adversely effected by the higher amp needs of the dual coils just because the dual coils are low ohm. The higher amp draw isn't the problem eGo batteries have with low ohm - and honestly, the battery in the eGo can't actually produce enough amps to get to where it would be a problem for the switch or the mofset. - It is single coil low ohm attys and cartos that are a risk - and the dual coils are actually a much lower risk than just about anything else.
I don't expect you to understand what I'm about to say, but it is for the benefit of the people who keep saying the dual coils kill ego batts (I have yet to find anyone who can actually tie a dead ego batt to a dual coil except one guy... and his ego batts were out of service and drained for a few months before he charged them and lost a batt while using a dual coil... ego batts fail all the time and leaving them drained and not storing them properly is a great way to kill them).
The mofsets driving an ego batt are sensitive to a drop in ohms. When a coil fails in an atty or carto, the ohms suddenly drop (usually anyway - but I'm not going to write two extra paragraphs describing the two situations where a failed coil does the opposite). That sudden surge is what kills mofsets. The battery in an eGo can't produce enough amps to damage the mofsets and neither can it produce enough amps to burn out a switch even if you were using a 1.0 ohm coil. They are a standard cheap li-on and not even in the realm of a mediocre IMR battery, let alone a good IMR - and it in no way is capable of producing the amps stacked batteries can etc etc etc. --- It is a failing coil with a sudden drop in ohms that causes a surge that messes up the mofsets. LR attys and LR single coil cartos are the most likely devices to experience that sort of failure at any voltage. Standard resistance stuff is far less likely (specifically considering the egos are regulated to something around 3.2 to 3.4v). -- When a dual coil has a coil fail, there is no sudden drop in ohms. in fact, the exact opposite thing happens. there is a sudden rise. In fact, the ohms double.
So, please don't let anyone get you worried about your ego batteries and using dual coil cartos. They've read bad information (and honestly, some of that bad information may even have been written by me at one point when I believed the same thing - I've done a little research since then, though)
