Here's what my BBS02 draws in max currents for various PAS levels per my wattmeter:
PAS 1: 3.1 amp
PAS 2: 4,7 amp
PAS 3: 6.7 amp - throttle at this level drew 15.9 amp
PAS 9: 15.3 amps
You should get a $15 wattmeter for debugging if you're trying to get your Dewalts to run that BBSHD. I bet they trip if you pull throttle, but might work for pedal assist.
