    Are cells always perfectly balanced?

    my 6000 mah 4s graphene yowoo batterie?s all have 1ohm of resistance per cell, but the volts aren?t consistent. Is this something i shoukd be concerned about?

    LiPo packs will very rarely have cells with identical voltages. In almost all cases, the highest-to-lowest variance will be no greater than 0.04V. However, if you have any cells with a variance greater than that, is suggest doing a full-cycle discharge/charge, and recheck the cell voltages. If, after a full-cycle discharge/charge, the voltage of the same cell is off the (approx) the same variance, then that indicated a good possibility that that LiPo packs might be bad.

      Btw you have 1 mOhm (milli Ohm) per cell which is astronomically good. Your charger is not a very precise instrument, is my opinion on that.
      By all means, all is good and all is well. Nothing is ever perfect, slight variations are normal.

        One assumes you are balance charging right?
