Buck converter

[robert1976]

I'm in need of a buck converter
Perfect would be up to 55v to run a 48v battery to step down to 42 volts 18-20amps to run on a 36v speed controller.
I found a 10amp one but it's out of stock. I was going yo buy 2 to and run parallel.
I wouls go for an adjustable one if there's such a thing.
Please drop links. Thanks
Hrs of searching getting no ware

thing is these things get hot and why the 2nd one i linked to has a fan on it but i doubt any of them will like running at the max limit for very long imo.

I be looking at cruising mainly rather then high ampage only running 200watt motor. If that all makes sense

Really ?

Are those buck converters designed to have their outputs paralleled up ?

Well its unlikley they are designed to work in parallel, so who can predict what might happen.
