192 E63 LG Batteries (the ones Francisco is using) can be made to fit in a leaf battery box. I guess that makes the battery pack twice the original capacity.
Possibly premade packs. 10 packs x 18 batteries and 2 packs of 6 x batteries

Yeah for sure - the energy density of those cells is very impressive.

I'm just trying to find the quickest approach and I think prismatics would be it. I reckon you could also use 18650 cells and a Tesla-style cooling loop, but it's all just weeks and weeks of work. My aim is to swap them out in a day if possible.

In this video the guy explains how retaining the vehicle's original BMS was the easiest way to keep the vehicle's onboard computer happy.
So I might try and re-pack a Leaf battery with a new BMS and wiring, but have it so you can swap the BMS at the last minute.
Looks like this confirms the problem and provides the answer http://evsenhanced.com/products/hv-batt ... ring-tool/

I am not sure how his extender battery boxes would go in the sunny summers here but his experiments and CANbus knowledge would sure be a useful resource.
