This might have been touched up on in another thread but hopefully someone can lay it out for me clearly and clear up any confusion. I intended on building a higher voltage battery (40s) and having difficult finding a bms built ready for that. If i found any they are bulky and/or expensive. That being said is it possible to use 2 20s bms in series while still being able to use its lvc and hvc as well as charging? Because the battery will also have a high amp output I was going to use a relay in pair with the bms. The closest thing I found to what I was looking for can be seen in link below, but only 35s. If doable please explain exactly how the wiring would be done. Much appreciated
