Found a listing on Ali Express where they are saying its "possible" to swap VW ID3 modules into a Nissan Leaf Battery Pack. They're suggesting it'll get 55/54/40/30kwh (too many numbers in the listing)
Its kinda an interesting idea so I thought I'd share in case anyone is interested in another unique project like @Dala
Its not entirely clear what BMS they're using but my guess is that it would have to be the Leaf BMS in order to minimize the conflicts between the Leaf systems and the battery. If it was a 40/62kwh BMS then I'm guessing its a Bruteforce replacement. If the person is starting from 24kwh then they'd need to upgrade the BMS which means they'd need to also upgrade the current sensor (Based on my experience). Plus if its in a Leaf then they'd need Dala's CAN Bridge to make it work.
Assuming they're using the Leaf BMS, the next issue is the description:
If we're running the 2 cells in parallel in the ID3 then that means each ID3 module = 3 Leaf Modules.
ID3 module has 6.85kWh
Leaf G4 Module has 1.6 kWh (x3 = ~5kwh)
A single ID3 module would thus provide excess capacity.
Only issue remaining then is that the BMS won't be able to fully charge the 55kwh to its fullest if its at the 40kwh setting... and I'm not sure how the 62 kwh BMS setting would handle it... could it? (I haven't worked with the 62kwh BMS).
Leaf module is 8.7kg; (x24 = 208.8kg)
ID3 Module is 32 kg; (x8 = 256kg)
So on that note its heavier and whether the full capacity is "accessible" or not could possibly determine if this is even worth swapping.
6.85kWh * 8 modules = 54.8 kWh total capacity
Assuming we can access the full capacity, thats
ID3 214.0625 Wh/kg
Leaf 191.57088 Wh/kg
So I guess the ID3 is more efficient if we can access the full capacity.
So from a back of napkin brainstorming... sounds feasible? It might also mean that these VW ID3 modules can be used in place of Leaf modules for anyone doing the Resolve EV conversion like myself and @Electric Land Cruiser or anyone else who is searching for modules for their conversion or upgrade.
Final thing to note is, these are the same sellers I bought my Leaf modules from. They were not shipped well as the packaging was thin and thus they came pretty beaten up. So far fortunately my pack is working well but just something to beware of. Hopefully 8 modules are easier to ship than 24 Leaf modules.

Some relevant numbers
- Listing is for 8 ID3 modules
- A single ID3 module contains 24 cells.
- The 40kwh Leaf has 24 modules, 96 cells total
- A single Leaf 40kwh module contains 4 cells
If we're running the 2 cells in parallel in the ID3 then that means each ID3 module = 3 Leaf Modules.
