controller whine

i finished installing my "for real" battery pack today and a quick 1 mile drive gave me virtually no whine or squeal! When i was still "testing" with my mixed pack i had used some old saggy batteries to get me up to 84v (1 pair sagged from 24v down to 11v while driving - using el cheapo digital voltmeter). today i purposely left everything else hooked up like it was, so the saggers appear to have caused the whine. i hope. i'll let you know if it comes back.
