I've got to admit to a bit of fascination with the higher energy density of 18650 format cells, especially the Panasonic NCR18650B which boasts 11Wh in a 50g weight battery. I built up a 500Wh pack for an electric scooter last year & found the cells to be beautifully balanced, so much so that I charge them without a BMS.
Recently prices on these cells have tumbled from $10-$12 down to $3-$4 ea. Has anyone else considered the possibility of paralleling the Leaf traction pack with a few extra kwh worth of these cells? A 384 cell pack (2p192s) in the trunk would add an extra 4kwh (~20%) to the Leaf, would weigh only 20kg & cost about $1500 to build. I'd make the connection at the charger behind the back seat on my 2012 model & simply let the AUX pack charge & discharge with the main pack. Maybe stick a 10A fuse in there somewhere just to be safe.
Thoughts anybody?
