And you would trust the chemistry in a pack who's cells had been dragged down below LVC plateau to hold up and be reliable in keeping a 3kg machine airborne while drawing 5C in climb-outs?
Don't fly anywhere near me with those batteries installed!![]()
Editor, it would depend on if I knew how the batteries dropped below LVC. Most of them just aren't being exercised or have already sat in a factory, etc., but those would still be in warranty. However, if one did buy a 47 or 48 or two, fly a couple charges off it, then forget to charge it, then that would be a case for giving it a go and seeing if it might work properly again. Agreed, mishandled or fried batteries aren't worth it, but as I mentioned in my notes above, I'd be testing them awhile (at least through two or three charge cycles) before I put them in anything that flew.
Best
