I'm looking at using a Multiplus II 48/3000 or 48/5000 with a bank of Nissan Leaf cells.
I was hoping to run in 16S - which would get me to a final voltage of 4.12v per cell so 65.96v total. I notice this is just under the Max DC input limit of 66v.
However, I'm not sure what the charger can charge to? Can it go this high or will I need to drop to 14S
Hi Slimf
I would run with 14S as this works perfectly ,as i run and use the 14S Nissan leaf cells with a BMS attached as well. As 14S is the perfect voltage to use with the Victron Mulitplus2, as this is what i have. Much easy to integrate than the Telsa cells.
And to date no issues recorded it just works well.

Thanks - This was the answer I was after. Damn, I have 32 modules, so am going to need to find another three so I can do 5P. Got any over there you want to ship to NSW Australia?! My modules are testing at around 350wh - so bit of degradation since new in 2011.

This set up uses the Leaf battery and a 48/5000 Quatro.
I have approximately 140kWh of Leaf cells attached to a number of MPII in parallel - 16s - Batrium etc ....
Max charge voltage of the MPPTs, and the MPII is 64v - which equates to 4v/cell.
4.12v/cell will lessen cell longevity.
65.96v is rather to close to the MPII max voltage.
Hi Rob
Im struggling finding out how to set my settings in the multiplus 2 for my 14s nissan cell setup. Would you share your settings?? I have set my jk bms to control my mppts. At the moment they are set to charge to 57.4volt which is 4.1v(pack is not yet equal and is between 4.08-4.13 when voltage is 57.4v)
Im from Denmark so of course need to set grid to Denmark.
Thank you very much in advance
