Cellmate and Tesla Modules

Hello all, I’m curious to see if anyone else is running tesla packs and cellmates. The modules were perfectly balanced prior to using them with the cellmates . Many charge and discharge cycles without balancing. Now that I’ve had the system hooked up running for about a year with cellmates and watchmon core that the cells are more out of balance than they were without bms balancer. Not a huge gap let’s say 4.06-4.02 but regardless it seems the balancing bypass function is making it worse .

Has anyone experienced this ? The cells are 2018 model s . I would hate for the cellmate to make the cells drift further if I were to ignore the problem.

Cheers!
