Ok, for the promised photos....
The Offending F35 Fuse, 10A. Described by EVTV as blowing like a flash bulb. Under Hood fusebox.

The Axiomatic Wake on Charge Module, P/N: 105200+A. Pins 1 & 8 are Positive/Ground and are shorted.

Two screws on top stabilizes the plug, 4 screws on the bottom. When one opens it, one is presented with grey silicone. ground strap to the middle of the bottom cover, and to the only screw holding the circuit board to the case.

With some careful picking, one can reveal much of the circuit board. It would be easier if one knew where to dig.
This Tranzorb TZ2 is part of circuit over voltage protection. But, instead of protecting the device, it blows it up.
It is a redundant circuit, and can be removed.
Incidentally, there are 5 pins opposite to the ground strap that penetrate to both sides of the circuit board. These may be a serial connection for programming. Normally buried in silicone.

I added a silicone sheet over the top of the circuit board before refilling with silicone. I chose to put the silicone back in in case it helped stabilize the board (only 1 screw in the board). Thus, if I need to, I may be able to open it up again without digging through 1/4" of silicone (I hope).
I left the Tranzorb TZ2 out, and am currently running without it. I'd like to split the wake on charge off of the F35 (also connected to the ECU). And, potentially add some circuit protection outside of the Wake on Charge module, so voltage spikes would get trapped before the module, and faults would not kill the module. The old Tranzorb was one of the first device on the pin 1/8 power bus on the circuit board.
The Azure is charging fine on 110V (albeit slowly). I am now up to an estimated 80 mile range which has the indicator pegged, and should be close to original specs (for a 11 year old van. Miles are just now hitting 16,000 miles.
I haven't run it to zero charge, but the estimated range seems to be indicative of the movement of the Full/Empty gauge.
It took a few days for the range to settle down. During that time I was regularly disconnecting the battery and plugging in and removing the wake on charge module before I was ready to refill with silicone and remount.
Without knowing the actual battery state, I presume the ECU was both learning my driving style, as well as the BMS evening out the charge level across all battery modules.

Since I bought the Azure Transit Connect as a non-runner (not my plan), I can't say for sure the cause of the fault. The EZTV suggested that they might have hit it with an 80A "starting" current from their charger. I only used a 2/10A charger on the dead battery I got it with. However, it is quite possible that the vendor before me also would have hit it with a high current charger.
When I got it (after charging), I was getting the Ford Security/Lock icon blinking (anti-theft system) which indicates a dead ECU, and the F35 fault.
