There is a 60 volt power supply, powerful, made of two latres (with decoupling).
It is necessary to charge a 13s8p battery from it (Li-Ion at 48 volts).
Interested in a simple current stabilization circuit ..
It would be great if it was controlled from the controller. I'll write the program, I don't have enough brains to figure out the circuitry. The currents will creep at 20 amperes .. well, picking up a suitable transistor, I think, is not a problem. I can't figure out what sem to apply.

An experienced colleague has already suggested. If anyone needs clarification, I'll sign it.

Is 20 amps for battery charging? Or what will be removed from the battery?
Don't want to take 8 amp charge current? Then you can take ready-made solutions from TI

you can look for a specialized controller (applied to a set with a motor-wheel), although it costs like an interplanetary starship.
You can do a primitive charge. PWM on MK with any transistor and three sensors: current, voltage, temperature.
Li-Ion batteries are charged as follows - first with a stable current, then with a stable voltage until the current drops to 0.
