It matters a lot what your commute is like.
Assume this had a 73 mile EPA rated range when New.
At 65% health that degrades to about 47 mile EPA rated range.
If your drive is 55 mph or less, in temperate climate, no need for heat, no need for ac, on flat ground, no wind, then you might see that 47 mile range.
But if you have to use heat or AC, or go over 55 mph, or have hills, etc, there's a good chance you'll be stranded.
And don't forget, it's going to keep degrading more as time goes by. So maybe it's 47 today, and 41 next year, or worse.
Might be better off buying two of them, and park one on either end of the commute. Then charge them each day and swap out when get to the other end.
Oops, also almost forgot to mention, that at 248 mV difference, that could be bad. Very bad. Would need to do a bit more testing to see if that actually is much worse under load. This number would be better if was more like 50 mV or less. As opposed to almost 5 times that difference.
If a customer asked me for my opinion on this, I'd say move on. There are healthier, less risky options.
