Smokin Cheap China Controller ?
I had my solar just a perkalaatin today, all 290 watts worth. 2 panels on the roof now, a few degrees off the sun, and my 90 watt portable directly on the sun. I was watching the amps go up all morni...

For a basic foldable portable solar panel system, this controller works great. It will get you to 14.4 to 14.6 volts, but I'd recommend a lot heavier wire gauge than the cheap 14 or 16 gauge zipcord wire, connectors and clamp ons that come with the panel kit. 12 gauge minimum, short a run as possible from controller to battery, maybe mount the controller near the battery instead, and run the long cord section from the panel to the controller, to minimize voltage and amp lossages. Most important, since you can't adjust the voltage on this controller. 14.4 v at bulk charge rate, minimum. 14.8 would be best, at the battery ring terminals, where it really matters the most, for the purists. 14.4 should get you 90% charged up, within reason.
