The castle controllers are advertised as industrial solutions that wouldn't necessarily be running from batteries, so I imagine their continuous ratings are accurate
see here
http://www.castlespecialprojects.com...ntrollers.html for their industrial ratings for different kinds of cooling.
Note the 'mamba max pro' has max input of 12V and there is no regular mamba max. I think they have been calling that industrial version the pro - its been labelled as that for quite a while now.
