I finally got 4 of these wired as 6cell in series(Zippy Flightmax 3000 mAh 3s 20C) resulting in 460g of total weight per 6s lipo:

Have discharged them down to 3.3V per cell with 1Amp and capacity was 3200 mAh. Well, not bad, will see how long they will last. First couple cycles cells showed some 8 - 10 mOm internal resistance, now they are in 4.5 - 5.5 range.

They balance perfect stock T500 ESP with ESC on a side and no canopy/battery tray modes (AUW 1870g).

Attached FDR from 4th flight... (just testing how they hold voltage, trying hard to bog heli and draw as much current as I can on stock ESP with +-13 pitch and +-9 cyclic).

PS: I have 2650mAh 30C in a mail and will test it when I get them.

Link corrected. This is 3s version of that 6s lipo

When I ordered 6s lipo was not available so I have to solder two of 3s into 6s one.
