I have been reading about this third party expansion pack for the Nissan Leaf (for 2011 to 2014). It is $6,500 in cost. They claim to be able to double the range of your Nissan Leaf. I personally think adding 660 pounds of batteries to a Nissan Leaf that only has a 950 pound weight limit is pushing it, but if you were to only add 400 pounds lithium ion batteries it would expand the range to around 112 miles on a 100% charge with all new batteries.
Edit: I calculate Nissan Leaf possible range differently than Nissan does. Nissan would probably put the range with the third party expanded battery at up to 134 miles. I do 84% of what Nissan says is the range and that is generally around what you get in real life (unless you are driving about 40 miles per hour on a level surface without heating or air conditioning).

This looks like a pack dropped in the back of the car and posted onto a blog. Regardless I would caution anyone that would consider something like this to do serious research first on the safely and track record of any company. Personally I think the entire concept here is too late and too little and has no profit for a company that does it properly. There are so many safety variables here it would take to long to list. Just buy an EV with the proper range.

That's a good start plus: Car weight load- suspension, braking, etc etc. Weight distribution/handling Mounting safety Changing crash worthiness Exposed to passenger cabin (long list) HV protection Failsafes Charging safety and isolation The list goes on and on...

There have been companies doing these mods for a LEAF for a long time. Many are bankrupt and there are plenty of LEAF drivers that have non operable cars now. Buyer beware and best of luck to anyone that can do this safely and turn any profit to stay in business. The demand is so low and the market is changing so fast it seems like more of a hobby pursuit than a product with any real lifespan.
Makes me wonder also even if one were not to get this big third party battery expansion pack. Lithium ion batteries are now improving in capacity. With the same 2016 Nissan Leaf SL using the same battery weight in five years it might get you 15% further just by replacing the lithium ion batteries with new ones. Instead of 89 to 107 miles in range you would be getting about 102 miles to 123 miles on a 100% charge.
I think I want at least 110 miles in range due to battery degradation and my 65 mile current commute. I am presently driving a 2015 Mitsubishi Mirage that is getting me about 41 miles per gallon.
