Sorry...
From a safety standpoint possibly... But how is using a 3.3V nominal cell in a device that has a 3.3V low voltage cutoff ideal? You would be able to use possibly 50% of the cells capacity considering it only charges to 3.6V. Far from ideal from a convenience standpoint when it is only an 1100 mah cell to begin with.
If you want to assume that I am calling them liars instead of asserting that they are perhaps ignorant or biased then so be it.
That is to bad. Some people enjoy using the best tool for the job and not taking unnecessary risks.
With the specifications of the IPV3 Li stating a 3.1V per cell low voltage cutoff, that would make the 25R a 77.5W per cell battery. The method used is to multiply the low voltage cutoff by the maximum discharge rate, or 3.1V x 25A. That means your are exceeding the maximum by only 6% at 165W. The issue with the invader is that when you do this same exercise, 3.3V x 30A for the VTC4 = 99W or 3.3V x 25A for the VTC5 = 82.5W. If we assume 100% device efficiency that is exceeding maximum battery capabilities by 17.5% and 31.25% respectively, equaling almost 3 times or more than 5 times the associated risk with exceeding the cells abilities. No longer an insignificant thing to do. This only pertains to using the device with a .1 ohm load as that is the only way the device is reported to be able to achieve 240W.
I use Mooch's testing for determining how much risk is posed by using a particular cell in a device. His testing has proven to be more than reliable and absolutely unbiased. The same can unfortunately not be said for some other specifications provided by vendors, Chinese trading companies etc. In the following table pay particular attention to the max amps column. Exceeding that limit is not a good idea.
As you are a new member than I am, that is one of the reasons I was trying to correct the false information in your posts.
