Swapped out the solar charge controller in the bed rack. New one has bluetooth so you can monitor the power input and output. Right now I just hooked a spare battery (not fully charged) to it since the rack is off and sitting in the garage. But the app is pretty slick. Turned on some of the LED lights on the rack and you could see the load go from 0.0 to .8 or so.
