    Excellent product! If conveniently set it can be used to charge lithium batteries with a solar panel. I found no other solar charge regulators that can be able to charge a 4s lipo batteries with a 20v foldable solar panel. It has two screws that can be used to adjust solar panel working voltage and maximum output voltage. I advise you to refer to solar panel and battery manufacturer to set the best working point and maximum voltage battery, respectively. If you use it to charge lithium batteries you

    Cheap and great battery controller. I use it to charge a LiFePo4 battery with a 50W solar panel. This controller charge my battery faster then a regular PWM charge controller.
