I saw that. Bigger battery for the "R" models, faster charging via the Charge Tank.  Unfortunately, I find the new color selections "Meh!"  I prefer the brighter colors of previous years.

I agree, think they should also allow optional ordering of any existing color panels. Not having SR in red is just wrong.

Don't think much has changed, zero is being very low key about features.

As someone who doesn't like change, the new 2018 Zeros seem perfect to me.    I do wish they had kept the yellow color, though.    Time to buy a new one before they make any real changes.

New bigger battery only for the R's and the weak half battery bikes?  Pea soup green DS (no thank you) black and white for the rest?
Oh and higher price for R's!
It's like socks and underwear for Christmas.

Agree 100%

To me the charge tank is the big deal this year!  6kW without extra charging equipment is pretty good.  Add a pair of digiNow Supercharger V2 and you can charge up fully in less than an hour!  For road trips, this is pretty darn good!

It is basically the best they can do with level 2 charging.  Level 3 charging is the next logical upgrade.

Really dissapointed it seems the new charge tank is not backwards compatible with earlier models, that was something i was really looking forward to as I don't like the aftermarket options so much. Also i like red much more for the SR so will be dissapointed if my next upgrade i can't get that color.  On the bright side I am at least not tempted to spend a small fortune to upgrade one model year again

I think the answer for the non compatibility of the 3.6kWh new power tank to the 2017 and previous bike is due to the new technology of the cells.

I think the new 2018  31Ah cells have new technology with much lower internal resistance ( higher power capability). The current sharing between all the battery brick must be equal the most as possible in a bike battery system. When you mix up some brick with different internal resistance the current will not flow equally over all these brick and will create problem. Normally while you are riding your bike, if the total current draw is 150A, then all battery brick must have the same current.. ex, if you have 3 brick then the current on each must be around 50A..

If you put a power tank with new technology and lower internal resistance there will be more current draw from that power tank than on the other brick of the main pack itself  and that's a problem.. cell might age differently, the SOC estimation might be tricky to calculate due  to rebalancing current flow between the bricks during power variations.. etc..

First impression... Underwhelmed 

Black, green and white and thats it??  Is the red paint that expensive?  A white SR is just wrong. 

$17k for an SR?  dafuq?

hmmmm.... 6kw + 3.3 + 3.3 is 12.6 kw, 12.6kwh in an hour is pretty nice for trips, and I guess you can leave the SCv2 behind when you are staying local, a pretty nice setup if you can handle the cost.  Just need a solid rack and top case for the SCv2.  Hope they improved the factory rack so it's not so flimsy.

It looks like the new 3.6 Powertank is backwards compatible according to Zeros website.  If it is added to an older bike, would it just be a matter of basic cell imbalance and discharge of the 3.6KW PT 31Ah cells first before the 29Ah cells due to the lower resistance?

It is not a matter of cell imbalance but a matter of discharge current imbalance (from one brick compare to  another brick connected in parallel to it)  I dont think a powertank (regular not long brick) could supply alone the entire current for the bike.. it have to be helped by the main pack monolith...  so i dont think it switch between one to two source... like the FX does depending of the SOC when added onthe fly

Thanks for the reply, do you think there are any long term battery health issues if the new 3.6KW PT were to be combined with the older monolith in terms of cell imbalance and charging?  I figure if Zero says the new PT is backwards compatible they are willing to warranty the dissemilar battery configuration.
