Hi all,
I've been reading alot of the threads and thought it was about time to post about my project, and get some tips/help for my build.
Its based on 3 complete Nissan Leaf batteries + 3 modules, giving me 147 modules in a 14S42P setup. I will be using REC BMS and Sunny Island 8.0 battery inverter since i have a quite large solar system (22.8kwP BIPV) This will likely grow a little aswell, as i have access to very cheap solar (I sell PV through my own company in Norway)
I have seen 2ways of connecting up the nissan leaf batteries, but have not seen anybody using fuses between the series. As my battery has a very high capasity, i thought it would be good to include fuses between the seriesin the design. Any input on this would be much appreciated!
My plan for battery voltage is to keep between 3.65v and 4.05v. I would like to maximize battery life over capasity, thats the reason i'm building the battery so large.
For busbars, my plan is to use 4x15mm solid bar either copper or aluminium.
Any preference between HRC fuses and MRBF fuses? The MRBF seems small and nice, but are actually close to twice the price. (i pay 5.5usd for 160a HRC fuses and 10.3 usd for the MRBF:

Some pictures from battery picking:
Lifted the pack out from my trailer:
Open the cover:
Lifting the back half out of the encapsuling
Dismantling of busbar:
2 batteries stacked up
