I wonder why the 2015 FX is heavier than my 2013 FX? The battery didn't change capacity. Do the new shocks and ABS add that much? I'd much rather exchange weight for more capacity.

BTW - Had a great time dirt riding in SE Utah on my Zero powered (2013 MX/FX Powertrain) e-trike. Running like a champ!
275 lbs 2013 => 280 lbs 2014 => 289 lbs 2015
The 2014 weight gain is due to a heavier, sturdier frame (+2.5 pounds), larger brake rotors, larger forks, and a restyled pillion-ready seat.
The 2015 weight gain probably comes down to wider wheels and tires, ABS, and potentially other components that weigh more.
Regarding the 10% improvement in battery pack capacity, it is my understanding that Zero is using the same batteries as they did in their 2013 and 2014 models, but have found a more efficient way of packaging them, thereby getting 10% more cells in each battery module. However they were not able to accomplish this repackaging with the "power tank" modules for some reason.
Is the 10% more cells something that has been stated, or is that your assumption based upon their terminology?
They can't add 10% more cells in parallel. 28 => 31 cells in series might be a possibility, but the Sevcon G80 controllers are already running as high as they can go with 28 series. 31 would push them right over, unless they have a new custom design.
Without any hard information to go by, I think they are likely using a one or more cells that are in total 10% higher capacity than the 2013-2014 Farasish 25 Ah cells.
