It could be yet another postmodern flim/flam just don't spend any of your own cash until you know you can get something in hand.
Wanxiang A123 seems set to play a major role in Stark future's future

Stark Future and Wanxiang A123 partner for Ultra-fast charge batteries
Stark Future and Wanxiang A123 team up for development of new higher energy density, faster charging, and improved heat control battery cells for next generation motorcycles – 10–15 minute ultra-fast charging anyone?

i hope they do that on the varg plataform aswell, not only on the future modelsWanxiang A123 seems set to play a major role in Stark future's future

Stark Future announcement could shake up the electric industry
Stark Future has entered into a partnership with Chinese company Wanxiang A123 that could have a far-reaching impact on the electric segment.

A123 is a LFP battery manufacturer. The announcement says Lithium Iron and 26120 cells. Very interesting turn for Stark away from Molicel. Keen to hear others thoughts about this.
Page 1 of this thread we discuss about Stark not working with Molicel anymore since they've introduced the 7.2 kWh pack.
From page 2 we talk about the new cell form factor 26120 announced by Stark in November (with Eve Energy at that time). Basically longer 120 mm cells will be packed horizontally and perpendicular to the motorcycle axis so they fit the whole width of the pack enabling much more efficient cooling, being air cooled by the external case on both sides.
Are you sure they mention LFP for Stark? I have not seen that and 330 Wh/kg would be quite a feat.

Thanks for the detailed reply. Here is where I saw "lithium iron" mentioned:

"Stark Future has announced a strategic partnership with Wanxiang A123, a Chinese company specialising high-power lithium iron battery technology, to develop and supply the 26120 cylindrical cell for their next generation of electric motorcycles."
It doesn't specifically say that Stark will use LFP in it's batteries, just A123 specializes in LFP batteries. I might have jumped the gun on my assumption.
You're right they do say that lithium iron phosphate (LFP) are the specialty of A123. In fact China is word leader by large in LFP technology so that makes sense.Thanks for the detailed reply. Here is where I saw "lithium iron" mentioned:

It didn't occur to me that next gen Stark cells could be LFP instead of NMC mainly because of LFP lower energy density. That being said LFP do have great benefits, as they're made using cheap and abundant iron instead of nickel, manganese and cobalt, so they're cheaper, easier and safer to produce, easier to recycle, less problems about overcharging and longer life thanks to much lower cycling degradation. Their main drawback besides lower energy density is their poor performance in the cold.
Now you make me wonder but 330 Wh/kg LFP would truly be groundbreaking so NMC is the safe bet.

Interesting. Marc with Alta used to join the forum for Q&A at VitalMX. I don't expect any future product reveals, but rather a reason why to not wait for the next version and buy now..Make your best questions for the battery future on thursday
People dont know Donut is a scam

they are at full capacity now on EX and SM production... there are delays again like at the first days
i think they are Happy with sales...
a Next gen Varg will be very wanted on the market, the most important update is the battery capacity... with the new colab with A123 i think is possible to reach 360wh/kg and with the same weight and size we can reach 10kw/h battery
lets see if Anton says anything on this matters on the Q/A on thursday

If they want me to convince to put my money on the table he better talks about future battery's being fitting for the current EX.
if they are doing this is because they are willing to "update us" with their next moves, at least to a certain extent... enduro electric bikes are going to evolve, and i think Stark wants to be at the top of the market, so a next gen Varg is innevitable in my opinion, with better battery and beter overall performance. Let's see
Unfortunately I think it's kinda like asking Honda if you can buy just the new engine to fit in your old frame instead of the whole new bike.
That does not fit with OEM business model.
Plus from an engineering point of view, you don't want any external constraint linked to retrofitting when you're designing a new bike, you want to take all the advantage you can to make the best possible bike. If you need to slightly alter the battery case dimensions to make it better fit with the new frame, you don't care that it won't fit in the old bike.
Sorry, don't put high hopes on this.

I'm more thinking smaller updates. Apart from the plug all the outer dimensions of 1.0 and 1.2 are the same. Doesn't seem like a huge amount of trouble to keep that the same in upgraded bikes.
This method of new model every year depreciates value fast, making people less likely to just buy the thing when the model is a year old. Because it will be strongly outdated and no longer upgradeable after a few months.
Also imagine having 8 iterations in 10 years for wich you all mandotory need to sell spares in the EU for the first 10 years. Doesn't sound economical.
Beta for example did improve their engines a lott, but a 2013 engine fits in a 2026.
Honda updates their bikes once a century, not every year.
