shiva2006 reacted to Tinbum in Need for RS485 or CANBUS communication for the Dyness lithium battery packI use a Teensy to read the data from my Pylontech batteries on the CAN line. You will need to make sure that the speed of the pi is fast enough to not miss packages. I'm sure you will find the protocol for your batteries with a bit of googling online. I would set the pi to just snif the data first and then you will get an idea. I find CAN much easier to use but it often doesn't contain as much detail as the RS485 or RS323 (Growatt batteries are an exception to this).
Regarding putting the batteries in series.
First are they designed for it? If not you will have to devise a way to balance each individual PACK or as soon as one pack reaches 100% SOC the others will stop charging. Not necessarily due to the bms but due to the battery chemistry.
