Hi guys, I have a 12s4p 30q dual focbox setup with 40A max current breaking.

Wondering if a bestech BMS ( HCX D223 80A ) can handle 2x40A of breaking power as the datasheet is rated at 4A or 20A charging current. I already have a supower 30A bms wich I could use for charging only but I like the E-switch on the bestech one. Or I could go with a simple switch like the one from electricskateboard.repair ?

What would you choose ? Thanks for your help !

Are you talking about motor min or battery min setting? The D223 is rated 20a charge current. You can set the motor min at -40a And the Batt min at -10a This is for a dual drive.
