There were a few people that requested the Chargery BMS to be added to my VenusOS Driver, but there is sort off already a driver. The one guy created a interface into the VenusOS and someone else linked it to be a driver as well. Other than that I do not know too much about it.
The JDB/LLT BMS that TTT refers too also originally comes from Will’s recommendation. He has it as the recommended BMS for 12V systems, but it works so great on 48V as well. They are prices very well and all their features actually work.
Daly is also popular, but that comes from when we used dumb BMS (i.e. no communication interfaces). Their new smart BMS specs are not up with the rest yet, but still very popular and easier to get your hands on. This is the most requested BMS to be added to my VenusOS driver, and the one I am currently working on.
