Obtained two of these. Happened to have several faulty 3S packs, so tested both against these and a good pack. They gave DIFFERENT results, they even gave differing results for successive operations!!! On one pack a voltage tester reported the cells at 3.7, 3.7 and 5.32 on a 3S pack, 7.4v overall. One tester reported this with NO red LEd or audible alarm as a 2S. The other reported it as two cells but also threw an alarm and red LED!! Went on to others, to similar inconsistencies. Seems pretty random when they find a fault what they do, they do flag an issue visually, albeit not consistent indication, but sometimes audible, sometimes not.......... One "in use" issue is that these have reversed connections so to see the lights the plug goes on backwards............so you have to be VERY careful to connect them the right way round. Would you trust these??

I've got one of these form another source on the 'net. They work very well and are surprisingly loud. I used mine on my tricopter. If there were some in stock I'd have a few more!
