These batteries are very poor. I ordered 4 x 3s and on arrival all four batteries were deeply discharged, one completely un recoverable. (I had expected them to be charged to storage voltage for transit.) I have been able to charge two of the batteries using the "NiCad" trick but they wont balance. After a short use the three cells are are at widely varying voltages, the highest at 76% and the lowest at 14%. The risk to my model in use, and to my workshop whilst charging doesn't justify the small saving in cost so for me a lesson learned. Banggood have a procedure for notifying a problem but its a drop down menu so as the batteries are visibly in good condition and the packaging in good order this avenue is closed to me.
