This step-up converter is powerful and versitile. There are two adjustment settings. One for constant voltage and one for constant current. I use this converter on my e-bike together with a 3-phase rectifier that is connected in line with the hub motor cable. This converter is adjusted to 45V output, but with a current limit of 6 Ampére regenerating charging current. The converter delivers 45V out when the input voltage is as low as 7-8 VDC. The constant current works perfectly. It delivers 6 A out when input voltage varies from 12 - 42 Volt. The converter was delivered in a thin plastic bag with some stuffing inside. Small dents on the capacitors, but the converter works fine.

Parte vino significativamente dañada y rota. Disipador térmico doblado, conexiones de alimentación agrietadas, aplastamiento de las esquinas PCB y, lo más significativo, una de las macetas recortables y una resistencia había sido arrancada de la placa. Inutilizable a la entrega. Ni siquiera lo probaría para ver si funcionaba por miedo a la electrocución. He solicitado un reembolso, al que Banggood ha accedido, y compraré otro ya que necesito uno para un proyecto. ¡Espero que la segunda vez sea mejor!

Part came significantly damaged and broken. Bent heatsink, cracked power connections, crush PCB corners and, most significantly, one of the trimable pots and a resistor had been ripped off the board. Unusable upon delivery. I wouldn't even test it to try and see if it worked for fear of electrocution. I have requested a refund, which Banggood have agreed to, and will be buying another as I need one for a project. I hope the second time around is better!
