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.

部品が著しく損傷し、破損しました。 ヒートシンクの曲がり、電源接続の亀裂、PCBのコーナーをつぶす、そして最も重要なのは、トリム可能なポットと抵抗の1つがボードから引き抜かれていました。 配達時に使用できません。 電撃の恐怖のために働くかどうか試すために、私はそれをテストしさえしません。 返金を要求しました。バングッドは同意し、プロジェクトに必要なものを購入します。 2回目が良かったらいいな!

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!
