I own (bought used) a 2012 Leaf SL with 11/12 bars battery. While looking at additional battery pack installation options, I found Hybrid Industries who offer 2 options:
1. $2500 12KWh battery pack which charges the primary battery over a 3 hour period.
2. $5500 24Kwh full battery pack in the trunk as mentioned in http://cleantechnica.com/2016/01/19/3rd ... to-48-kwh/
Does anyone have any first or second or third hand information about the results of such a modification?
The $2500 secondary battery seems like a good insurance.
