BMS for lead acid?

[Kep]

I have a 48v wet Lead acid battery bank with 12 ea 4v batteries. Is there an option for a BMS for charging only? like a 13S 160-200amp charging only BMS.
Have not heard of a BMS for this type of battery. Anyone know if this is done on wet lead acid batteries?

Just curious because what I have been doing is once a year moving the 2 source cables to one of 4 different locations to pick up the 48v on the bank when I clean and service the connections.

Pretty sure that lead batteries are self balancing from a physical and chemical perspective.
But you can certainly add BMS like protections such as a low voltage cutoff.

Periodic equalisation takes care of flooded open cells from a balancing point of view. Flooded cells like a good agitation to prevent acid stratification so that works out nicely.

Thanks that's what I thought the equalization was doing. I move the cables around to just ensure I don't favor any cell configuration is all.
It is easy to do when cleaning the connections once a year.
