Review on Dorhea LM2596 DC-DC Buck Converter Step-Down Regulator 4.0-40V To 1.25-37V DC 36V To 24V To 12V To 5V Volt Power Supply Module With LED Voltmeter Display Compatible With Car Motor Buck by Kyle Hong
48volt MAX for my opinion
These are either miss labelled (not really the 'HVS' version) or the description is just wrong. I tested one with 12 volt input - worked just fine. Then tested it on a battery with 47.3 volts - worked fine. Then tested it on a battery with 50.3 volts and it blew immediately. Vendor needs to re-edit the description where it says, "4.5-53V." That is just wrong.Addendum - in all honesty, I posted the question about 54 volts after I ordered these things and Cbas responded with a terse "no". But when they came, I tested one anyway. They are cheap and they work with lower volts, so I'll keep the rest of them.
- Works as expected... No instructions included but easy to figure out
- May not be compatible with certain types of batteries
