I would suggest giving them some time, let them finalize the specs, costs, warranty, etc.There lies the problem. It WILL last 8-10 years but probably not much more for the average driver. Mine mathematically should last me 38+ years because I will probably only charge it, the large battery, once a week if that because I only use my truck about 4k miles per year. But for the average driver, that's not the case.
(Many EVs have an 8 year warranty on the battery - isn't that a California regulation?) Their FAQ says 10 to 20 years lifetime.
Not sure why you would pay for the big battery? 4K miles a year is about 77 miles/week. Unless you do a long trip every month? With the DC Fast charging, what's the big deal with stopping a few times to recharge? Or take back roads and maybe get 300 miles on the small battery at 40MPH?
Leafs seem to be the ideal of upgrading batteries. I think you can take the original release Leaf (75 mile range) and upgrade at least to 150 miles range (maybe 225?). This weeks GM Ultium press release says they expect $75 per kWh next year. And 20% more range in the same size pack.
Hopefully Slate will get into battery upgrades. As a DIY company it should be right up their alley.
So what if there is a 105kWh extended pack available in 3 years, for less than the current one costs?
And how degraded do you think these 10 year old Slate packs will be? If they still hold a 20 or 30kW charge, perfect for moving into a home's solar setup.
