Abstract: In some aspects a method of monitoring an electrochemical cell stack can include measuring an anode voltage difference between a first anode tab from a plurality of anode tabs and a second anode tab from the plurality of anode tabs, measuring a cathode voltage difference between a first cathode tab from a plurality of cathode tabs and a second cathode tab from the plurality of cathode tabs, and calculating a difference between the cathode voltage and the anode voltage. In some embodiments, the first cathode tab and the first anode tab can be located at a proximal end of the electrochemical cell. In some embodiments, a distance between the first anode tab and the second anode tab is within about 5% of the distance between the first cathode tab and the second cathode tab.
