I have tried 2s, 3S and 6S batteries all with the same result. I hopefully someone can shed some light on the subject. I have been considering getting a 3010B as an upgrade since I have been impressed up to this point. However, I am having second thoughts since I purchased this unit 7/31/2011 and have less than 100 cycles on it (mostly 3S 2200mAH and 1S 500Mah).
According to our engineer, this message won't affect the use of the charger. But you can try to short circuit the output, check if this message still appear.
