Hello everybody.
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:

BMS.
Fuse, contactor and pre-charge unit.
Some of the connections.
Shunt.
LCD panel.
Comming together.
From the back.
Thermostatic controlled fans on top.
4 pcs M10 bolts on each bank.
