While factually correct, I think this statement is a bit misleading. The Infinity is Current Limited at 2A - which is not a bad thing, I happen to think it is a good thing. It will increase the longevity of the batteries and the pcb and reduce risk of "venting". This 2A limitation WILL result in LR atomizers causing the protection circuit to kick in, depending on how low the resistance is and what voltage you set the device to. However, LR atomizers are generally used to increase power(P=VI) in devices which do not have a very high voltage, e.g. 3.1v to 3.7v devices, and results in shorter battery life. With a variable voltage PV (~3v to 6v) you do not need to use a LR atomizer to attain a satisfactory level of power(P) at the atomizer.
