    Good product, but cannot deliver charging current of 5A, unless there is proper heatsink on the two diodes and the two mosfets. This may also be due to RCS being bigger than 0.04Ω. In any case the existing heatsink is not correctly glued underneath the components, as it touches only partially some of the heated parts. Even worse, the metal heatsink touches the pins of some other components and there is danger of shorts and damage. Furthermore, in my unit, the dual led is soldered the other way around, and as a result, when it charges a battery, the blue led is on, and when the battery gets full, the red led comes on. Nevertheless, it is a good mppt charger. I attach the Charging Profile and its Diagram, taken from CN3722 datasheet.

    The board is very simple. It seems to work perfectly fine thouh, but I am unsure how clean the output is.
