Depending on your use case, you might be best apt to look at a converter vs just a charger. This way you can also use it to supply current for 12V use cases as well (Among other things). I assume this is a system you want this connected to at all times.
This will charge my pack at 45A on appropriate AC and can also run my 12V system when connected to AC. They sell other amp options, but 45A is a good balance between cost and speed.
I also have smaller LiFEPo4 battery chargers (Approx 10amp) that I use for other battery work thats more portable. I generally only use that for smaller packs that I have setup for remote battery systems though.
If money is no object I'd go with either the Victron IP65 or IP67 models. Both will interface with your phone to tell you exactly what is going on. The IP65 comes in various ampere ratings but for a 200 AH LFP I'd go with the biggest I could afford. Divide the ampere rating on the charger into 200 amps to get an estimate of charge time and figure on about 20% more. Charge time will vary based on how depleted the battery is. I have both of the above, and a few good older chargers but the Victrons are the only ones I use with LFP batteries and the IP65 is my go to charger now days.
I don't think we have enough information to answer the question here.... Or maybe its just me confused. If its just a battery charger you are looking for... Look for a one that supports LiFEPo4 and spec it at to support what the battery shows as charge rate (Usually between .2C-.5C).
