When you see an EV conversion like that, it's always because the person didn't any reach and didn't understand it would hurt their range.
More like to make a cheap build work.
If you don't have a decent DC-DC converter but you do have an alternator, and it is still hooked up to the remaining parts of the original engine, and your range does not matter, why not?

It would just power the 12V bits, albeit at max 75% efficiency versus the 90% from the DC-DC converter.
It would thus eat into the range more than the DC-DC converter would.

You could also charge a separate battery for the 12V system and not use alternators or converters altogether. But then you'd have to watch both battery charge levels.

For confirmation go to people just like you.
For education go to people unlike yourself.
