LiFePo4 single cell charger?

Has anyone charged a single 3.2v LiFePo4 cell? Any recommendations on chargers for single cells?

I just watched a video on this. Standard benchtop DC power supply can do it. Search Youtube for LiFePo4 Top Balance. I have a Hanmatek, comes in handy for lots of things like this.

Doing this in your bus, I have no idea.

If your cells are large, sometimes top quality high-current low voltage PSUs come through eBay pennies on the dollar.

So long as the adjustable voltage includes the 3.45-3.6V range.

Recently 60A for $75 iirc, maybe TDK Lambda? old school heavy duty stuff. . .

All you really need is a power supply that has a max voltage of 3.6v and a max current. I have a little 2amp board that charges one cell. They are just dc-dc devices with max voltage and current limits. I have a dozen of these little unit to charge individual cells. works great for small ones.
Big ones need another solution.
