I don't think so. It's supposed to be rated for 10A, and I was only pulling 5.1A through it, and one just like it (bought at the same time from AS&S) powered the same system on N56ML for all that time with zero problems. I think it was infant mortality...it literally rattles now, as if a contact broke completely loose inside. I borrowed the one from N56ML for now, but will install a 30A DC version shortly. I flew it almost every day last week, and the only reason I quit after only a half hour today is because it started hailing on me... Mark Langford ML at N56ML.com http://www.n56ml.com
