Yes they are harris rc lipos
see here:
Harris RC 5000mah 30C hardcase

Curious thing is when I emailed them re these discharge graphs, I get no answer. Strange yes?
Regardless I will reset the MMM esc to a cut off of 3.5v / cell, if it's averaging or taking a sample based on the packs resting voltage, it "should" cut off around the 15min mark on this graph which is what I want.
PS, a Reedy 5000mah 20C hardcase lipo dropped to 5.89v on a full charge amp burst and the lvc didn't trip there either.
