How low do you let the battery go down before charging it? Is it good for the battery health in long term to go under 10 % before recharging?
Some cars should not go below 30% f ex..

The small battery may need some charging during winter/storage period. Manual says charge with 1/10 of capacity. That is 0.4 amp. But a regular scooter charger is 0.8 amp. Will that be ok?

I charge my battery when I need more range for my next day's travels.

If your battery is at 10%, you need to charge it. You can't go far on 10% charge, and you can't go fast on it either (it drops into Eco mode at just a bit under 10%; I can't remember the exact point).

Put a good smart battery maintainer on the small battery for winter storage and you'll be fine. It will adjust the charge appropriately.

I don't have Elettrica, but in general:

Lithium battery lifetime tend to be sensitive for charging them over ~80% of their capacity. Assuming Elettrica battery can be charged 'full' (as they typically can), it would be good to charge it only up to 80% whenever feasible. No other harm done charging them up to 100%, but it shortens the battery lifetime.

Again in general, Lithium batteries won't mind if they run until 30 or 10%. They don't like to be empty for a long time (say, several weeks, or months), but are happy to be charged between a small% and 80% as often as needed. The bottom end is typically not linear in voltage delivery, so I'll guess less than 10% is a bit non-practical - as stated above.

Actually this 80% is interesting - kind of 'small print' in EVs. You can have the full range OR longer battery lifetime, but not both with Lithium batteries.... and of course the real life is often a mix, sometimes you'll need the whole range and sometimes not.

My typical pattern is to plug it in and leave it until I'm ready to ride again. That almost always means it charges to 100%.

If that means I'll be buying new batteries a bit earlier, well, the scooter is still fantastic. It wouldn't be nearly as convenient if I had to time my charging to keep it below 80%.

I believe you are among many other EV users with this.

In my car, a plug-in hybrid not a full EV, I use the remote controlled timer that comes as a standard. I have quite a good idea of an average time it takes to charge at home, so I'll set the charging time accordingly a bit short - ending up with around 80%.

Would be even easier if the app would let me set the target charge level, which it does monitor and display - but this app too is optimized for a '100%' user, not for battery lifetime. At least here a lot of plug-ins and EVs are company cars, hence making the battery lifetime optimization mostly irrelevant for the users - it will last the lease period
