Why bother mounting the controller so close the the battery? If you get a controller with remote volt/temp sensing, it can be anywhere. Then it doesn't make any difference if the voltage drop loss is before or after the controller.
Remote volt/temp sense has nothing to do with getting maximum voltage into the batteries. Maximum voltage into the batteries (minimal voltage drop) is exactly why you want the controller as close to the batteries as possible. All remote sense and temp gets you is remote temp and sense, nothing else.
