Battery needs a MINIMUM continuous discharge to meet your needs...the controller 'pulls' current to it's 25A max limit, the battery doesn't 'push' current at battery's 50A max limit.
Having double your required discharge capabilities will provide you with a nice always-cool unstressed pack that should last quite a while.
thanks for the help after doing a bunch of research and then forgetting about the amps i was worred it might blow but what you said makes scene. Thanks again.
