They are also highly unlikely to explode if they Briefly exceed the rated tolerance of the
batteries for a short time in short bursts. Anyone exercising common sense, and responsibility recognizing the limitations of the device and
batteries installed and using the device as it is intended are probably not going to have a problem.
Joyetech sold this as a 150w device and removed some of the limiting software to allow greater performance with Sony VT5s but anyone using a 150w device with 10a
batteries at 200w constantly because they have to prove they have a bigger private part than anyone else around deserves to have it blow up and take them out of the gene pool!
Just my unsolicited 2 cents!
