Combining channels on 2x15A dual motor driver

I need to supply a DC motor with approx 20A continuous. I want to combine the dual channels into a single channel in order to achieve this.

My board is the DFRobot 2x15A lite and is based on the BTS7960.

The analog voltage is applied to both m1_pwm and m2_pwm inputs simultaneously. What is the best way to combine the channels?

1) Run both channels in the same direction (both m1_en & m2_en high). Wire M1 & M2 + outputs together and M1 & M2 - outputs together?

2) Run the channels in opposite direction (m1_en high & m2_en low). Wire the motor using M1 + and M2 + outputs.

In theory, what you said is feasible. But I am not sure, we havent tried it before. If you really want to do like that, you can try to do . If you succeed, thanks for your sharing.

Have a nice day. :)
