It’s been awhile but I’m back and wanted to get my board back at it again. But when I plug my 6s lipo on my focbox en plug te xt90 key I get a huge spark and it melts my xt90 plug. First I thought it was the battery because it was old or something. So I just received my new 6s lipo and got my wires re soldered. First I tried a 3s and everything was fine but than I plugged in my new 6s and it happend again. Do you guys know what is going on? Hope you can help me.
