Yes. Dive-X specs for the BlackTip are 123 minutes at cruising speed, with 2 x 12Ah.
Current specs posted for the Go! are 220 minutes at cruising speed.
I can only add that my personal experience with the BlackTip is that it goes much longer than 123 minutes, but am not able to put a specific number on it.
The Go! has 150 W-Hr more battery capacity onboard (432 versus 582), so I would certainly hope it would give a much longer burntime.
I've had the same experience - with smaller batteries, even.
I have one set of Dewalt 10aH batteries that I did a 112 minute dive on the SS Copenhagen in the Atlantic off Fort Lauderdale with last year - and on the return trip, that included towing my buddy back (also diving sidemount with two 85's and a DPV) to shore for the last 500 yards or so after his 9aH batteries died. I forget how many passes we made up and down the wreck site, but put in behind the SeaWatch on The Ocean restaurant and scootered out and back. I still had either one or two bars left of battery life on the packs when I took them out after we hosed everything down at our hotel.
