You spent good money on a very nice battery, so don't cheap out with your tools like amateur-ish hacks like using a cheap PSU - which aren't designed to have voltage from a battery on their output terminals.
Much like being a fine furniture craftsman, and using a sawz-all to make your cuts.
Your original choices were fine. Another recommendation for an actual Meanwell *charger* (not just one of their psu models) is also fine.
For a non-critical system, I recently picked up an ExpertPower EPC1220. 20A, but has a CV of 14.4v - unlike most in this range that drive to 14.6. It also is rated to stop charging when current drops to 2.5A - which also helps keep the charger from spending too much time for too little effort on large batteries just sitting in the CV stage for longer than necessary.
So I measured it when charging my 100ah Talentcell:
No load voltage measured at clamps: 14.5v
Voltage under load with battery charging reaching CV: 14.44v
Current at charge finished: 2.5A
So yeah, not a Victron. The lower 14.4v CV seemed reasonable, and also stopping at 2.5A means it isn't trying to totally stuff the battery either. Might be a consideration for you but even at 20A - that's going to take a long time with a 208ah batt...
