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 è venuto significativamente danneggiato e rotto. Dissipatore di calore piegato, connessioni di alimentazione incrinate, schiacciare angoli PCB e, più significativamente, uno dei potenziometri e un resistore erano stati strappati dalla scheda. Non lo testerei nemmeno per vedere se ha funzionato per paura della folgorazione. Ho richiesto un rimborso, che Banggood hanno accettato, e sarà l'acquisto di un altro come ho bisogno di uno per un progetto.

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!
