I think it would be safe to assume the SS9 will also have the same battery. I wonder if we'll get an option to buy this new 21 kWh battery and retrofit it to our bikes.

[BigPoppa]

I believe Energica has said before that while they'll try to make any future battery developments an upgrade for existing models they weren't going to guarantee it. If I recall correctly, they said it would probably be more cost effective to just get one of the new models since the bulk of the cost of our bikes is the battery and associated electronics (which would also need to be swapped out if you dropped in a newer battery).

As always I claim no definitive answer here...just what I seem to remember reading elsewhere.

[Sklith]

You're probably right to assume it'd be way more cost effective to just buy a new bike, especially since a new inverter will also be needed to deliver more power.

[MVetter]

I doubt it. Do you know what sort of monstrous overkill the Rinehart is?

You're probably right to assume it'd be way more cost effective to just buy a new bike, especially since a new inverter will also be needed to deliver more power.

Why deliver more power just because the battery has more capacity? The idea of a larger battery is mainly to increase range, not performance.

enjoy, new 2020 EGO

So it does. And claimed lower weight... If efficiency is the same (and given a faired bike with very similar-looking aerodynamics, don't see why it would be worse), the range should be at least ~70% more... Sounds promising!
Looking forward to seeing actual road tests, and hoping they also make a sport-tourer with with this battery with less aggressive riding posture.

Do you mean different than the SS9?

Not necessarily -- just less aggressive than the Ego, but still with fairing; Personally, I'm not interested in unfaired (i.e., naked) bikes at all.

Bigger battery = more amps = controller can draw more amps = more power delivered

[Sklith]

Bigger battery = more amps = controller can draw more amps = more power delivered

Yep. The inverter may be the bottleneck once a higher amp battery goes in.

[Crissa]

If you want more range and not more speed/toque, then you don't care if the inverter is the bottleneck.

There is a limit to how much can be put to the pavement by that bike, and another limit for what is safe on streets altogether; so changing the controller or inverter would need more than that.

[DonTom]

Bigger battery = more amps = controller can draw more amps = more power delivered

Wrong.

It means more power CAN be delivered.

IOW, it means more amps are available. If you have a billion amp battery and only draw one amp, the power delivered is still one amp times the battery  voltage but for a MUCH longer time. Works out much like KWH. Cannot have too much, just do not use it, unless needed. The need does not change with the battery, but with the load.

You can never have too much amperage in a battery. Not for anything. It will not change how much current is being drawn, wattage used stays EXACTLY the same, you simply have more available. Having more KWH available doesn't mean it must be used, Same with SUPPLY amperage. Voltage is different, as too much can destroy stuff. So can too much current form the LOAD, not from what's available in the battery.

[Crissa]

Well, more amps available means more damage when there's a short, but everything else, yes.

Change the battery amps, changes the range of the bike.  Change the motor/inverter/controller... You're changing the bike performance curve itself.  You could do that already, and they do, which is how there's different models.

Use the same fuse as always, and that "problem" is also solved.

Your fuse or breaker needs tobe able to handle the over amperage when it fails; the energy culd exceed the structure of a fuse (I recently had a fuse explode when I accidentally put more than 8x the amperage through it it was supposed to fail at.  Whoops.)

But yes

Wrong.

It means more power CAN be delivered.

I guess this is what MVetter implied, at least I read it that way.
