New Lithium Smart 3x200ah bank is unbalanced and charging disabled

Just turned our new battery bank composed of 3 Victron Lithium Smart 200ah batteries (all gadgets installed, BMS, cyrix-li load, etc..) and it says cells are unbalanced and goes to charge disable mode after charge with our MPPT, tried with the Multiplus and does exactly the same.

as we were checking the app we noticed the same battery (our battery 3) looks very unbalanced and one of the cells reaches up to 3.77v and then the system disables this battery from charging. And off course the remaining 2 end up not completing their balancing process.

Is this normal? Or are we missing a step?

Thanks

Dear sv The Dream,

A slow charge should do the trick... So try to charge with a 1 amp current.. More is explain via the link above.
