Can someone please provide a schematic of the whole system especially showing how the BMS is wired? I'm technical but not quite to the level that I can decipher the posts and put it together.

Start by reading the manual for the BMS.

I have, thanks. What I would specifically like to know is that if you have a pack of 7 modules and each module has 2 cells for a total of 14 cells for the pack does that mean that you use one BMS for the pack? In your case, when you've used 6 packs initially does that mean you used 6 BMS? Thanks in advance.

Correct. 7 modules=14 cells on series.
Only one BMS needed.

You can put as many cells in parallell as you like.

Hi offpist, thanks for sharing this awesome work.

I am currently off-grid using Outback charge controller and Inverter and an ancient 460Ah 48V Lead acid battery bank. These old batteries are a real worry.

Having swapped my 2011 Leaf's battery for a newer one http://www.mynissanleaf.com/viewtopic.php?f=51&t=21997&start=120 my plan is now to make a similar storage system to yours with the old pack. I will try not to ask too many stupid questions. Before I begin I want to know if you are still happy with your design or if there are some things you'd change, especially now that there are 2 year's worth of developments since your first build?

Thanks,
Niall

Hello, nice project, i would like to do the same but i would like to ask you your experience with the battery pack, how many cicles did you do? do you see some changes after the time? how much charge discharge the package?
thanks in advance.
