Great work what is the cost of the new belt and sprockets?

Can someone post a picture of what the battery looks like with the case off and what the cells look like.
There were some articles recently of a Zero battery engineer criticizing Tesla's cylindrical cell batteries and the writer was fanning the flames with a catchy headline 'Tesla can learn a thing or two about battery design from Zero.' Interesting.
I can think of a couple of reasons Zero's advice is to leave the bike plugged in:
It's the simplest advice to give.
It gets people into the habit of plugging in, thus reducing the chance of them finishing a ride at a low state of charge and then not using it for months.
They've calculated that the battery pack will still have well over 80% health after 5 years even if left plugged in all the time.
Leaving the bike plugged in is the most convenient thing to do. People like convenience and Zero wants happy customers. If they suggested standing the bikes at 40-50% SoC, inevitably people forget and get on a bike with half a tank. It might not be enough juice to get them to their destination, or it might shorten the trip out they planned. Either way they'll be pissed off and frustrated.
It's unlikely that many people will own their zero for more than a couple of years and they might only suffer a 5% drop in battery health in that time. They either won't notice it or it won't make much of a difference to them.
For long term owners, improvements in battery technology will result in nominal capacity increasing 50-60% during five years. The price is likely to drop too. Range is unlikely to be an issue for those owners, but they might consider a new battery pack rather than a whole new bike.
Five years is a long time for Zero to develop new technologies, integrate new features and improve the product. The original bike might be kept as a runaround or given to a family member whilst a new model is bought for main use.
After I posted I found this site that appears to sell Farasis batteries... is it bogus?Ouch! I hope you're not too banged up.
Thanks for the info, this is great!
Are Farasis cells available direct to consumers or only to business?

Farasis is still a tiny company, 35-40 in our US R&D / dist facility, and 400 in our chinese assembly plant (most are robot techs and warehousing workers)
If we follow Dow Kokams approach and sell directly to consumers, and have someone burn down an apartment complex and sue us. We could easily get sued out of existance. So at this point, we like to keep close control of our battery cells, and that means that no cunsumer sales for the time being.

What is the peak and continuous discharge rates of the 2016 29A cells (I understand the 2014 25A cells were 7C peak and 4C continuous)?
Thanks
PS I've attached the data sheet for the 25A cells. Would love to see the data sheet for the 29A cells
Ouch! I hope you're not too banged up.
