Burst Profiles - discharge testing

OK,

A couple of you are aware that I have been implementing 'variable profile' discharge testing of my own. Well now it is ready, and the calibration complete. I now have the capability to replay DPR-50 in-flight log files as a discharge profile 'on the bench', as well as setting arbitrary profiles.

For my initial two studies I selected a 2S PQ2100XP and a 2S 'Impulse Power' (Saehan ProLite V2) 950 pack. The discharge profile I chose to put on them was one that I had seen for one of my electric aerobats: 8 seconds low C discharge (~6C) followed by 2 seconds of high discharge at ~20C - all on a repeat.

The graphs of delivered power, voltage and temperature is shown for these two packs, and I invite some interesting discussion.
