No battery cell voltage window option for GTR?!?!

Any other gtr owners a tad miffed over this?
How is it that the older boards can do this and the latest gen gtr has this valuable information not available?

 

Would have been nice for monitoring battery cell health. Maybe with the new battery design of the GTR model the costs vs. consumer want removed it from the list of features. Is the GTR line the first generation using 18650 size cells?

Back when I was a bit too geeky, nerdy a log of battery health used in flying quads and other platforms was kept. There is a device called a lipo ESR (equivalent series resistance) meter. Internal resistance (IR) increases with use and lower air temperatures. Once an individual cell developed a higher IR relative to the others it was time to consider replacement of the battery. Simple device. In a full charged battery. Plug in the main first, plug in the balance port plug. Guessing there is a access port somewhere on the GTR battery for Evolve to run a diagnostic? The Giles ESR Meter, early generation is designed only for up to a 6s battery. Another accessory Evolve could market. But guessing too expensive for most to consider. For reference. Purchased the Wayne Giles ESR Meter directly from him many years ago. Old memory, but I think I paid $75(USD).
