What I don't know is whether S, SR, SR/F and SR/S bikes are assembled in Asia also.   I haven't seen a VIN on any European listings.
I have a 2025 SR/S (Netherlands) which has a “PAG-number”.

I'm happy if I'm wrong. I understood that any assemblies in Asia where for international markets. US market bikes would be assembled in US.
Aha, now I understand, I’m in Europe  ;) .

The only viable option is importing fully assembled bikes in small numbers, but the big bikes are not assembled outside US yet.

Are you sure about that? I understood that a 2025 SR/S was assembled in the Philippines?

Guess I have to answer my own (original) question, after reading the manual, which says:

The 12 volt battery is charged from the motorcycle’s power pack. During regular operation and when connected to a charging cable, the MBB (Main Bike Board) will monitor the 12 volt battery’s charge level to ensure that it’s charge level is maintained.

So, the 12 volt battery seems to be monitored / charged when the charging cable is connected, (and I assume they are talking about the cable of the main battery).
By the way, I did not yet check if the voltage of the 12 volt battery does indeed go up to 13+ Volts when I charge the main battery, will do that next time.

Thanks for all the answers regarding the 12 volts battery. Now that I’m reading reactions about lead acid batteries I’m prepared to read advices about changing the cooling fluid on my SR/S soon too  :D .

but wouldn't it also charge every time you rode the bike too, sipping off the main battery?

Yes, that’s right, but the reason I asked is my situation in winter, when there’s frost and salt on the road. I don’t ride the bike in these conditions, so my plan was to put in the garage after “the last ride” and charge it till 55%, and after 3 or 4 weeks till 60%, a few weeks later till 65%, etc, in that manner I can span two or three months. That’s why I wondered if the 12v was charged too in this way, but it doesn’t seem te be the case.
Strange that you have to leave the bike with the contact on for an hour or so to keep the 12v in good health, I guess I’m still in the “internal combustion”-mood, where you cannot leave the contact on for such a long time without damaging the circuit  ;) .

So, let’s say I charge the bike till 55 %, and when the charge is finished, I put it on contact, disconnect the plug, set the chargegoal to 60 % for the next charge, and turn of the key.
The next time I connect the plug, so, without turning on the key, the main battery is charged but the 12 v is not?

Hello.

A question about a 2025 SR/S: I understood that the 12v battery is charged from the main battery when the bike is in use, but when I charge the main battery without turning the key on contact first, will the 12v battery also be charged at the same time, or only when you turn the key on (for example, to unplug the cord from the bike at the end of a charge)?

(I am an Electrical Engineer with extensive experience with Electric Vehicles and am CTO of an EV company)

In that case, a small question: I learned at this forum that the 3rd gen Zero bike balances the cells every time you charge till a set percentage, after reaching this percentage, and before ending the charge. Would you say this is true?

10
At minute 25 the reviewer tried to get stupid with the power and snapped the drive belt, resulting in having to call one of his coworkers to have the Zero hauled in a van
When I studied at the maritime school to become a naval engineer, one of the teachers always said “people who can use their hands in combination with their brains can achieve a lot”. Didn’t know then that it also would apply at (electric) motorcycles  ;) .

As far as I know, the battery cells will be balanced to the charge target you've set. By default 100%, but if you set the target to 60% via e.g. the app, the bike will balance the pack as soon as it has reached 60% SoC.

On the Gen3 bikes, you will notice this on the dash that the bike continues to charge (and consumes energy) although it has reached the set SoC target and remaining charging times is 0m. Typically (in my case) takes between 5 - 10 minutes.

Well, until now I only charged to a target, and at two times I was there by chance when it reached the set target. And like you say, the target was reached, remaining time was zero minutes, but charging kept going on with amps and kw’s slowly going down for about a few minutes (first time that I noticed it was for like five minutes, second time somewhat less).
So, in other words, if you’re right, I guess I balanced my battery without even knowing it  ;)

Something I just remembered: one time the target was set to 70%. When I went to the motorcycle that evening the charging had ended for a while, but the shown SOC was not 70, but 73 %, now I realise that maybe it might have been balancing for those 3% ?

12
Hello.

I understood that the battery cells will be balanced when you charge until 100%. Will this be at the “normal” 100% or do you have to select the extended (110%) charge?
And, if the bms is balancing, does it say so on the screen, or do you have to guess what it’s doing?
By the way, how much time does an average balance take, more or less?

It stays free. Since there is no DCFC with Zeros, they don't need to be so careful with locking things in.

Energica locks in, Zero doesn't.
Charged my bike for the first time this afternoon. I’m afraid I have to disappoint you (or not); the plug locks at the beginning, and only unlocks when you turn the key after charging is complete (or maybe also after you turn the key while charging still in progress, still have to find that out). (2025 SR/S).

It's also "only" breaking just under 7 amps, I'd be more wary if I was in a 110V country.
Well, my charger can be set to 6 - 8 - 10 - 13 - 16 amps, where 16 is the most the circuitbreaker can handle in the average household installation in my country. I guess I will use 6 or 8, where 8 gives about 1,8 kw/h.

Shouldn't charging stop when you turn the motorcycle on?
Yes, later on I remembered that the dealer said (during an earlier visit) that charging stops when you turn the key, but I don”t know if this is the correct way (for the motor’s electronics).

I also called the shop of the granny charger, they told me to pull the plug on the motor-side because this will first disconnect the communication-pin, but later on I thought that normally the motor-side plug is locked, so this wouldn’t work. Does a Zero lock the plug or does it stay “free”?
