We are rejecting batteries in our cycler during discharge because once cell difference may be greater than 200mv. We pick that number out of the air. Our batteries have 3 cells. The batteries are new and have <1% error. What percent error in cell voltage spread would I expect during the discharge or charge? Should we look at cell imbalance at the 100% charge. We send the battery out with 50% final charge.
During the charge cycle the TI brings the cells back together.
