Crosspost from the Fenix Systems battery thread:

Looks like someone has actually put a 40kWh in a 24kWh car, with full instrumentation working. 180 miles in a 2011.

I'm guessing some one figured out how to teach a bms how to translate.
I wasn't expecting that for like another year.

This could be a game changer for folks with the older Leafs. There was a 2012 for sale nearby for $2500 recently. I thought about buying it just to use the batteries for solar backup but didn't since it will be years before I'm ready for that. However, buying the car and spending $7500 to put in a 40 kWh pack would yield a $10k 40kWh Leaf. Not a bad proposition if everything else was OK.

I follow this LEAF battery upgrage swap story out of interest but it is extremely unlikely to ever be an option for me, or for the lion's share of 24 kWh LEAF owners. Consider:

1. Nissan is not interested
2. A full fledged car garage is needed due to the equipment requirements, battery heft
3. LEAF expertise is needed
4. The LEAF does not travel
5. Battery shipping is *expensive*, and 40 kWh lightly used but in good condition packs are a rare bird indeed.

How many garages in your town fit the bill ?
How many 40 kWh packs that meet your requirements are available locally and are not prohibitively expensive to transfer ?

I went through the hassle of all of this to get myself a new 24kWh pack. I agree that its not for the majority... And it was a ton of work... But very worth it. I saved ~$4.5k on the battery.

If I could have done this instead, I would have gone for it in a heartbeat.

I am not normal. I am also not rich. For those of us that can't afford a Tesla or newer leaf, this is... amazing. :-)

1. Nissan is not interested
Why is this even listed as an issue?
2. A full fledged car garage is needed due to the equipment requirements, battery heft
I got that
3. LEAF expertise is needed
I got that
4. The LEAF does not travel
Leafs can be shipped 1000km for 200€
5. Battery shipping is *expensive*, and 40 kWh lightly used but in good condition packs are a rare bird indeed.
I shipped a 40kWh battery for 260€ across three EU countries

What?!

No technical support
No warranty
No garage access

If a problem occurs after installation, where does the car owner go ?

I should easily be able to drop the battery using my pallet jack.
Probably do it outside so I can roll the battery inside the garage to take it apart.

In the US I have shipped several vehicle long distance over the years.
I had my leaf shipped from Chicago to new mexico, total cost to my door was about 50 cents a mile start to finish to have it carried by truck.

To have a leaf battery shipped across the US would run $250 to $500 and that's delivered to where I work where there are about 20 commercial loading docks and dozens of forklifts. Delivery to a truck loading dock just about cuts the price in half compared to home delivery.

Now let's see if some one does it with an e+ pack.

$7500? Might get a salvage one for that price. You really think Nissan will sit on its hands if this guy's business takes off?

I would have preferred he put together his own pack. Might be a bit easier that way.

I didn't read the article in much detail but I have to imagine the pack was out of a wrecked Leaf and this will always be a cottage industry. That's fine with me and I doubt this would ever become a high volume business. Best case, it could get to the point of the Suburu engine into a Vanagon type business, which is fairly mature now and well supported with easily available parts for the swap, mechanics who have done multiple swaps, etc.
