"... full regen at 100%, and no serious cutback of power right down to 0% ..."

Same here, I really enjoy being able to use the full 100% range of the new battery's capacity.

My last two batteries were from the previous generation and were partially defective. Each ended up losing about 30% of their original capacities, which was enough to trigger Zero's warranty. I actually had the third one on order from Zero (under warranty) when I did my multi-country tour in the summer of 2023 in Europe with the defective second battery. I just had to make do with about 150 km of range.

Yes, if only one phase is available where you are charging, then your upper limits are going to be 220 V and 16 A, thus below 3.5 kW (includes conversion losses). The two built-in chargers in the Zero can take 16 A each and are using the first two phases, the rapid charger can draw 32 A from the third phase to add 6.6 kW of charging power giving the total of ~12 kW.

I am limited to a single phase and 16 A thus charging at home with 3.3 kW max. That is good enough with my Tesla, so largely sufficient for my Zero. As you probably already know, the vast majority of public AC chargers will give you three phases thus giving you 6.6 kW, and even 12 kW if you have the additional 6 kW rapid charger in the frunk.

It is worth trying. In comparison of my SR/F, I still don't fully understand why my Tesla M3SR+ which is 6 times heavier and has four large wheels only requires 1.7 times the energy per km.

What was cause of all these failures? Did you have pay for the new batt or did they warranty it?

There is a 5 years warranty from Zero / Farasis on the battery, which applies to anyone who has taken resonably good care of the battery as described in the manual.

From the symptoms, not a continued and linear degradation, but a sudden loss of capacity after (in my case) about 30'000 km. It would seem we are dealing with mechanical / physical problem with how the pouches were assembled in the factory leading to a sudden capacity loss which is, I must say, quiet well managed by the BMS. The "degraded" batteries are still perfectly usable, in fact I did a 800 km trip last summer with one. You'll have less range and the SoC is less reliable, but I still had all the torque I wanted.

As for Energica, they are also dealing with the need of using high density LiOn batteries, thus must be facing similar assembly chalenges. I don't know about their reliability but their warranty is smaller (3 years or 50,000 km). You will have to pay to bring it to the same 5 years as Zero: https://www.energicamotor.com/us/extend-your-ride/

My DSR/X with charge tank from France .Maximum height is 8cm

Thanks a bunch. Now I can see that there would be a bit more space left on the DSR/X, than with the SR/F.

Thanks for the SR/F frunk with charger picture. Makes it easy to see the difference.

I recently noticed something else. Scenario: charging to 100% SoC and then riding downhill. Back then with the old 14.4 kWh battery I would not get any regen braking. Not so with with the 17.3 kWh battery. It appears as if the software caps it at 15.6+ kWh for charging, but not while using regenerative braking.

My Zero mech changed me the motor sprocket at 71'000 km, but due to wear (from rusting) to its inner teeth. Seeing what that meant for you I am glad I didn't try myself. Thank you for documenting what you have done.
