In another thread I posted on a bunch (180 on hand now) 170ah surplus lifePo4 prismatic cells I got. I have been testing them in 1P4S 12V configuration and they are testing excellent.
So now its time to move on to the 48V pack(s) that I need for my solar. I found this thread of a build with 4P16S batteries and a lot of good information.
It seems that the 4P16s config is the best choice for me. My present inverter can only charge and discharge at 100 amps although I may add another in parallel in the future. I picked this 200A 16s BMS by JCB to use with the proposed 4P16S battery. https://www.aliexpress.com/snapshot...d=8140593047615742&productId=1005002650532071
For weight reasons, I am planning on splitting the 4P16S battery into 4 modules.
I realize its a LOT of battery for my inverter/solar setup but cost is not a factor and the batteries should stay in the 30-80% SOC range giving a lot of life and reserve for multiple dark days.
Would really appreciate any input before I actually start building a 48V battery. I still have lots of cell testing to do in the meantime.
