Gostei do produto, bem elaborado. Deveria ter vindo com um folheto ilustrativo.

I unpacked this converter and it looks exactly as described on the pictures. The wires are easy to connect, and I charged an e-bike accu pack (7S, 29.4V) from a car battery (12) with it. I had it connected for 5 hours, and slowly increased the voltage on the blue connectors of this device. The output voltage was very stable even the input voltage got down due to the load. summary -- it worked perfect, well done banggood!

BG438443191 Isto não é uma fonte, mas sim um abaixador de tensão contínua.

The unit is OK. I tested it for 24V input, 11V output ay 10A current. The output voltage is relatively constant (from 11.5V no load to 11.2V at 10A). The temperatures are: 100 dgr.C for transformer, 100 dgr.C for one heatsink and 80 dgr.C for the other.
