So I have been charging my 2s and 3s lipo batteries with this charger. I hook everything up correcty and I try to charge either of the batteries I get a error [BATTERY VOL ERR CELL CONNECT] The weird thing is that the 2s lipo stopped working and got this error then I ran the 3s lipo and tried to charge it and got the same error. I was wondering if anyone has had this problem before and knows what is going on.
