I currently drive an Nissan Leaf, and I am also very interested in Solar systems.
So I started thinking an battery from Nissan Leaf would make a good storage for solar power I normally export to the grid.
So, I got a hold of a battery pack from an wrecked Leaf, and started building.
First of all i had to make it about 48V, and to do that i have to put 14 Cells in series.
Each module has two cells, so its only 7 modules in series and 6 in paralell.
Then I can use 42 of the 48 modules from the battery pack.
This may be expanded with more modules later, we will see.
For battery management i am using this unit:http://www.rec-bms.com/BMS9R.html
