Can I control the discharge current from the batteries to load output on my MPPT 100/20 Charge Controller?

I have a MPPT 100/20 Solar Charge Controller connected to Lithium batteries. The load output is connected to my load (a pump).

In the settings I already limited the charging current to 5A. Can I also limit the discharge current from the batteries?


Thank you!

It is not possible to limit the current going to a load otherwise the Voltage to the load will drop. This is Ohms law.

If you want to limit the ammount of load on the battery then you have to switch loads off or use fuses / circuit breakers to disconnect the load if it goes above the limit that you want.
