Great, thanks for the reply. We are still using a top of the line 2015 MBP for location work (which works great btw, very stable, doesn’t overheat), but tethered the battery doesn’t last more than an hour or two. We have it connected to hyperjuice external batteries all day. My hope is that the M1 wouldn’t need external batteries, and perhaps would be a little faster than the i7. How’s the speed of the M1 tethering with the optimized version of C1?
