Some of these BMSs are not very tolerant of heavy loads... the heavier load may have triggered the BMS to shut down and go into self-protect mode. It can take a few hours to days for voltage to recover. Isolate the battery from the parallel connections and give a few days of no load time to recover and reset.
After that, use a regulated power supply and connect it to the battery to charge. You only need a slight current, usually less than ten amps. Set the power supply up at the base voltage 54 to 56 volts. Last, supplying charge voltage on and off several times can wake up the BMS, but again, I would only try this with a regulated power supply. The bad news is they may have killed the BMS... once you do that, it's a hard sell for most manufacturers to cover under warranty.
