Long term (4 year) A123 26650 findings.

[zeropointbug]

Yeah, and they should be around 150Wh/kg. I would like to see some Headway cycle life data, just to compare.

I just froze the pack down to -25C (-13F), did a discharge on the 720i, reported 148mOhm off the start, then just decreased from there until the end of discharge of 64mOhm.

Will post a heated test of 165F once I'm done.

EDIT: Finished the heated discharge, pack temp was 167F when I started the test, discharge function on 720i, cell iR went down to 28mOhm/5 = 5.6mOhm/cell.
