I think 10-12Kwh in a small pack could worth looking at.Cool stuff. I'm really interested in what the car thinks is going on, like, does it now know it's got a 48kwh battery instead of 24kwh, or does it think it's still 24kwh but that you're managing to drive round at 8-10mpkwh?
This is unlikely to happen both for physical (how do you secure each suitcase? in a dedicated racking system that then can't be used for anything else? are there always live electrical connections in that racking?) and electrical ones (is each suitcase connected in parallel to the main pack? how can a small suitcase give out the same amperage in a main pack? what if the suitcase is at a different state of charge when you connect it?)A suit case type you can remove if you need the boot!
@Mike Schooling has already put an extra 24 kWh battery into the boot of a written-off Leaf here in the UK. He says it works fine, but I will let him explain about the effect on the BMS, etc. 12 kWh module may also be a possibility after the 5 year warranty expires...Cool stuff.

Yes we have already done it in the uk about a year ago (another thread on here) to a crashed gen1. It works, we can charge all 48kwh and drive it around the yard here and have confirmed capacity by running it down with the aircon and heater a few times.
We got to the stage of working out the packaging (to make it safe/legal) and then wanted to do some road testing.
The weight is what makes it a non starter really. I fitted the cells and prototype enclosure (not connected, just for physical weight which is about 350kg) in my running gen2 leaf and it ruins the existing range and makes the car a dog to drive.
We expended a fair bit of effort playing about with the suspension (mainly lifting and 'hardening' the rear) but it doesn't really improve things.
We also investigated the insurance issue and found some companies willing to cover it for a reasonable price (i would say about 20% above a standard leaf).
That's as far as we took it.
It technically works but makes the boot more or less unusable (in a gen 1 it is the same height as the 'hump') and ruins the handling of the car.
Carlos Ghosn has already promised (in Japan) a 48 kWh Nissan EV for 2017 launch... Do for me perfectly!Wonder when folk will start believing that some super amazing 60kwh Leaf won't be hitting the market any time soon.
30kwh for sensible sized cars, leave the tank sized batteries for the tank sized cars.
