Brushed Motor Controller Suggestions

Looking for recommendations for a stout brushed PM motor controller powering dual wheelchair gearmotors from 8S li-ion (33.6V max). I can’t find any specs on motors but I pulled them from a Hoveround MPV5 and I believe they pull about 40A inrush each from a DIY shunt? Anyways I keep blowing up BTS7960 modules left and right. Currently split between the Cyton SmartDriveDuo-60 and Kelly KDZ-48-20-1 (I really wanted to make KDS-series work but I need reverse), both around $180 price point. Any suggestions? Cross-posting from Facebook group. Thanks!
