this will work for some. as you know, get the basics here and someone will mod it to work better. 3 Kwh is a bit borderline small but at $3400 it is a price that is doable. now, someone will figure an easy way to wire it up to the pack to essentially extend the pack. As for me? if I was in a situation where I needed it, it would be a tough call. portability means not lugging it around using valuable space when i dont need it which would be probably 50% of the time or more.
but, then again, i have preached public charging and its really all about money.
back in the day, i drove a Datsun (yep that what it was) 280 ZX. it was cool and first 5 speed i ever had. but it was also known as the "poor man's vette"
it was sporty, sharp looking and fun to drive but MUCH cheaper (and slower!) that a Corvette
the LEAF to me is basically the same thing. all the fun and benefits of EV driving but at an affordable price. adding $3400 (and as we all know that cost just STARTS there...) to the price of a new car to add range is like buying a car brand new and then pulling the engine out and putting in a bigger one right away.
now, i used to know people who did EXACTLY that and i never understood it then and i dont understand it now.
but public charging is not created equally. I am almost embarrassed to complain about the lack of quick charging (only have about 15 in the region) when some people here dont even have 15 L2 options. so ya, extra pack, its a good thing. this one is $3400 but it opens the door. maybe the next one will be $3,000 and have 5 Kwh... (then i might change my mind!)
