Well here is the rehearsal hall equipment with "no cables".
https://www.dropbox.com/sc/viruwv9ar2spzrj/AAC8PwygA2kKuhqj3I2wN18qa
The overview with music stand for 4 up and room for two iPad's or other gear. Detaches and folds up and is stored on the side for transportation (Velcro straps).
Front cover still in place gets removed and stored in back held by magnets.

Side view showing wireless EV mic, amplifier with Bluetooth and line input, all of 90 Watts @ 4 ohms. That's 22 Watts per channel at 8 ohms. Can't max it in a 33 x 40 ft. room without complaints about being too loud.

Other side showing essential water bottle and Starbucks holder, and the necessary voltmeter. Luggage rack retractable handle for transportation. Mic stand for handheld.

Speaker removed to show battery. JBL CBT-70J speaker makes a significant difference for this application.
Battery used is Powersonics.

Battery charger used is this (normally $115).

Volt meter is this.

As to how long this will run without a recharge depends on the load off course. The current draw is around 0.8 amps with max I've seen of around 1.2 amps. The continuum of sound going thru the system will make a significant impact. This unit ran without a charge for three days of ~ 8hrs of on time per day at a chorus retreat YMMV. If you're looking to power a DL1608 and WiFi gear it will draw about 2-2.5 amps. I would suggest a 40 or 50 AH battery if you need to run for 8 hrs. This one is 35 AH. I would not discharge the battery below 12V. See the discharge curve from the spec sheet. For grounding see the pin one discussion on this forum.If you need a sub I would put it on it's own battery.
Cheers

Hi WK154,
Thanks so much!
Am going to look in to the possibility of using a small 1# battery that is on a charger all the time.
But gotta have clean power.
The bigger battery, DC-only option looks good for some generator gigs.
Good health, Weogo

UPDATE:
After a dozen or so gigs in the venue from my original post the problem has been solved. The issue was that the docked board would not react correctly when I tried to change any settings, it just go a bit wonky. The Neon Light bar sign transformers were interfering with the interface on the DL1608 somehow. My last gig this weekend, we unplugged the neon beer signs and the Mackie worked like a charm.
My previous work around was making sure that the I turned on the board and synced to a my go to preset with nothing muted before I go to the gig. Very nerve racking as all my volume adjustments were only input gains and physical speaker volumes on my powered speakers.
