Hi Forum, Dala here from Dala's EV Repair. I recently did a budget upgrade on my 2012 Nissan Leaf, and thoght this might make for a very interesting topic here also. It is almost a step-by-step video, with cost breakdown at the end. Cheers!

This seems to be a bit of a no brainer. Source a very cheap 2012 Leaf 24 with 8 bars left, and a 30kWh battery from a recent write-off. Swap over and stick the old battery on the garage wall for storage. It would make a nice winter lockdown project.

Dala, well done on the upgrade and the technology involved in the process. Could this be done with a 24kWh to 40kWh upgrade?

Great videos. Funnily enough Youtube recommended your videos to me before you joined this forum.

Then after watching a few of your videos suddenly you've joined the forum. Spooky. :)

The Can bridge stuff in particular is quite interesting.

I think you can upgrade all the way to 62kWh

That would be handy come the time. 24 to 30 isn't that significant, but 40 or even 62 would be really handy! There's a couple of 40s on eBay now. I wonder whether the physical size might vary though.

Yes, my personal car is a 24->40kWh upgrade, and way more bang for your buck! Always go for the 40kWh pack if possible


Yes, it's possible using the CANbus adaptor sold by EVs enhanced (NZ).
Actually, I'd say my homegrown CAN-bridge solution is superior. ;) I can do any 24/30/40/62kWh battery into any generation Leaf (ZE0/AZE0/ZE1).

Great video ,would be great to do a conversion in the future when my pack is badly degraded .
Have seen a few 40kw packs for sale lately, are the dimensions the same as the 24/30 packs or is there a few more modifications needed?

Robert Llewellyn of Fully Charged fame has a Gen 1 Leaf which is getting a 40kWh pack. Looking forward to the video when released as delayed by C19.

Physical shape is exactly the same. Weighs a bit more (kg listed in the video)

Yes, I wonder which CAN hardware they settled for...

I do like the idea, but as i commented on the video, the issue seems to be getting hold of packs.

I've had half an eye on ebay for packs for probably 3 years now, as i've been toying with the idea of some DIY home storage, and actually the pack pricing defies any sort of logic. I would expect as time has gone on, for the batteries to become more available and cheaper, as more cars are broken. Infact, they're more expensive than ever and availability sucks.

Looking just now, there are three batteries available (which is actually better than i've seen). However pricing is junk. Theres a 24kwh pack for 3.5k, a 30kwh pack for 3.5k, and a 40kwh pack for 7k.

At that pricing, the numbers just dont stack up. The 24kwh pack is clearly ludicrous. The 30 pack is maybe close-ish, and the 40 pack is again, ludicrous.

But even taking the 30kwh pack as the best value of those three; If you happen to have a degraded 24kwh leaf its worth maybe 6 grand? Buying a battery for 3.5k, plus shipping plus the CAN bridge means your now 10k in the hole, and have an old LEAF with no warranty support and potentially insurance issues, whereas 10grand buys you an actual 30kwh leaf, with years of warranty left, not to mention its a younger car with better resale value. It just doesnt make sense at those battery prices.

I think you really need to get under £100 per usable kwh before it really starts making solid economic sense. IE ~2.5K for a LEAF30 pack and £3.5-4k for a 40 pack.

Can i ask where you're looking, and where's a good place to look ? I'm interested in a 40kW pack (or a 60; but rarer than hen's teeth?), with a view to upgrade my old 24kW sometime in the next year or so. I recall Mike S suggested a 40 could be found for 4.5k and a breaker offered one 5k delivered (tho no info on SoH). I've not seen much on ebay, and was guessing that a specialist EV breaker would likely be the place to go ? As an aside - would an EV ever end up in a traditional breakers yard ? I'd guess not - as they buy from insurance companies (??) and wouldn't take on a wreck with the safety/experience issues that an EV comes with compared to their traditional fare...

BTW, Dalathegreat has a very useful thread/website on the work he's done at his EV garage in Finland; i'd highly recommend it for those looking to learn about fixing or modifying their Leaf.

I've only really been looking on ebay. I would suspect the reason they are so rare is that various specialists have the market tied up much like you suggest. They all end up in the hands of specialist breakers, and probably the big companies doing upgrades or conversions have deals with these specialist yards so get first shout on packs, and as a result they just dont appear on the open market. Of if they do, they appear at seriously inflated prices because of supply constraints.

Probably also, when you look at costs, my figures above are based on the economic case for upgrading an old LEAF. Its possible (or even quite likely?) that the case for an EV conversion is actually somewhat different and thus people in that market are willing to pay more per KWH, than makes sense as a LEAF upgrade. I've seen many companies selling the 5kwh Tesla modules for £1k or more, £200 per kwh... easily double the figure where it makes any sense for a LEAF. Personally, given manufacturers are approaching $100 per kwh for new assembled packs, charging £200+ per kwh for a used salvage battery module is insane. But thats market forces at work i guess, supply/demand etc.
