Victron Energy has a nice application book on their web site the have super products, I used them on my 64 foot GOFAST. Besides products they also discuss battery technologies and applications. My hard copy is 15 years old.

Yes, if you buy batteries for N * 100K $money, spending more money
on your charger is a good investment.

But if you have two batteries doing float-charge/long-run/tiny-load,
in a benign environment in a corner of your lab, the internal
variance between batteries in that same production lot, will
overshadow any imaginable benefit a fancy charger could bring.

They are for the same reasons they suffer cyclic use better.

But for a float/long-run application, it makes absolutely no difference.

Never attribute to malice what can adequately be explained by incompetence.
