How to deal with more than 128 Cells?
Hello, i have connected 128 LiFepo4 Cells (18S 8P) via 8 pcs "All In One Module V490" to an "Controller Board V4.6" and that all is connected via Can Bus to an 48V Victron System.
Now i want to extend my Storrage to another 64 LiFepo4 Cells - total 192 Cells (16S 12P) (maby in the future more). How can i extend the System in that direction - i am fine when i have to use two Controller Boards - to IP adresses, ... But how to make shure that the Victron get all informations??
Next thing is the Shunt - i have now one 500A/50mV Shunt installed, but i want to use two 500A/50mV Shunts in parallel (i have limited space in hight - the 1000A Shunt will not fit.)??
So how to deal with that all? Any ideas?
Thanks so much for such a asome project! Best regards, Ingo Pirker
You could compile the code to handle more than 128 cells, this has never been tested or required until now, but you can just change a single number up to 256.
Hey - thanks for the answer! To compile the code should be not the issue. But what number should i change - can you maby describe this a bit more?!
And i will send you some good stuff to :-) Paypal - https://paypal.me/stuart2222

oh thats easy - thanks! Will try and give feedback - but will take some time (shippment of the batterys will take 4 - 6 weeks)
Sorry i forgot to give a info if it works - YES - verry good and verry stable:
Thank you so much!
Fantastic - another user was having problems with a single bank (high voltage) of 128 cells - have you ever tested that?
my old installation was 128Cells (16S 8P) - that was working perfect - so no issues there
