I would have to look it up but iirc the ahr rating was 113
O.K., so perhaps the electrical interface has changed, but the video only claimed that the dimensions and the connectors were the same.

Cool. Hopefully they will eventually standardize on this pack for LEAF 2011-2018 replacements rather than maintaining multiple battry production lines and materials inventories. One can hope... :)
I noticed you're still working with polymers.

The 2018 batteries without liquid thermal management will suffer the same as all of those before them. The only thing we can hope for is that 2019 Leaf will be engineered with a TMS system. My prediction is that the 2018 will get about 107-113 miles at normal freeway speeds.

We can hope, but the higher energy density in a passively cooled pack sounds worse than earlier packs, not better.

We can only hope Nissan changed the default charge level to 90% and were so excited over Pro Pilot, they simply forgot to mention it...

Given Nissan's propensity for doubling down on mistakes, I doubt that.

Given that various model year LEAFs have already demonstrated different rates of capacity loss, there is no "same". It may be better, or worse than all LEAFs before it, or it may fall somewhere on the existing spectrum. Since there may be a different chemistry at play, no factual statement can yet be made outside of someone in a laboratory. Numerous DIY EVs have used LiFePO4 cells, for example, without pack cooling and have not suffered the rates battery degradation we have witnessed in previous LEAFs.

Or, to put it another way, if they use a chemistry with the same thermal properties as the 30kwh pack, this one will be worse. Otherwise we'll have to wait and see.

That’s putting it the same way. :)
