This is where things COULD get dodgy. If you poke around the world of eBike forums and come to know the trusted sources you'll find these Meanwell power supplies are safe for our chemistry, reliable, and used by many. Where things go south it's usually because of some boob on YouTube or on a forum draws crazy conclusions and strikes out on their own and tries to use some other product or variation. OR is a truly goofy user that doesn't put his multimeter to good use.
The ones you linked to. I don’t see where they say they are for lithium ion charging. I saw the designation when looking at 12v chargers. Some were for SLA and some for lithium ion. Is the real difference only in output voltage of the charger? I know 12v SLA and 12v l-ion charge to different voltages. Other than current, since that is also adjustable in your linked chargers, is that the only difference? Seems like yours are just power supplies and not a designated charger. Maybe they can be the same, as long as they are set properly?
You're safe with the Meanwell listed.
We're told to use only the manufacturer charger because very many are confused about what the LVC, low voltage cutoff, nominal charge, and finished charge levels are.
For example, a 48V battery fully charged is 54.6V. A 52V battery 58.8. And those are HARD maximums to NEVER exceed. Yet someone will read that some cells can be charged to 4.3V and THAT is where things begin to fall apart...
