DIY 'Chargenectifier'

After a brief search on eBay for '48v rectifier', I discovered that creating your own charger can certainly be a viable project at significantly lower costs compared to traditional options.

To kick off this exploration, let’s take a look at several examples I've encountered.

It’s essential to consider how you will adjust the voltage unless you can locate a device that comes pre-programmed.

(I apologize for the links; I'm using the eBay app to share the items and copy the URLs.) These units appear promising because you can connect them in parallel to achieve your desired voltage or have the flexibility to scale them as needed.

So, what am I overlooking? It feels as though there must be significant information or resources missing which is why this topic hasn't gained more traction. Based on insightful comments shared by @ChrisFullPower in another thread, I am intrigued about constructing a charger using used rectifiers. The eBay search for '48v rectifier' confirmed its feasibility at substantially lower costs than retail products. I am starting this dialogue to uncover various possibilities. However, proper voltage regulation options must be established unless pre-adjusted solutions are available. Apologies for the disorganized links, as they are derived from the eBay app. Many of these power supplies look promising for parallel connections to hit voltage targets or for scalable options.
This looks like a great price but would require more connectors. What am I potentially missing here? It seems this must be a notable gap in knowledge, or it would have reached mainstream discussions already...
