Hello Stuart, my LTO pack have per cell 2,1 to 2,6v and its work good. Its round about 48v pack and this is What i used 40 Peace from the all in one v490 own creation. In Maximum there are 40x 12 cells= 480 cells

Hi Michael. Connecting two controllers to the same CANBUS isn't going to work, there are just too many cells for the DIYBMS system to handle in 1 controller.

Hello Stuart, I think it also but how can I do this. It is possible that we can connect 2 or more controllers over the rs485 for calculation and push it on the can bus out. Or I must create a can bus hub what calculate all controllers and sent it on one can bus out. Thanks and best Regards Michael.G

Hello Stuart I am again, can you say me what can bus adress do you programming in your code and can you say where is the pos in script for changing. I will also test on my Deye hybrid I mean I saw a multi bms list so that I can install mor bms on can bus.

thanks

All the code for the can bus is in the file named canbus.cpp.

You still won't be able to put multiple controller on the canbus, it just doesn't work like that.

Hy Stuart, ok I understand. In this case I make a can Bus hob and use 2 controller on one victron. I have create a controller withe 3 can bus and one rs485 and display for later Funktion. See picture[](url)
