Mistake busbars ?
#5
You variance due to difference in individual cells are easily 10mOhm or more ofr used cells.

Therefor your design is fine, since you have bus-bars with resistance which is a lot less than IR-variance.

Secondly, is only relevant at extreme currentloads.

And even with small busbars, the problem is stressing of front cells compared to back cells, and some extra charge-discharge cycles locally in the packs whilst it eaqualizes  - so some coulomb-losses (<5% of the imbalance-charge), and some wear on the cells - not optimal for teh pack, but possibly optimal in other regards such as access to maintenance. You get some and you loose some.

Your current* design is fine, dont sweat it.
