POWER SUPPLY INCLUDING THERMISTORS DISPOSED ON ANODE ENDS OF BATTERY CELLS

Some embodiments provide a portable power supply comprising a housing having a plurality of sides defining an internal cavity. The portable power supply further includes a battery cell assembly positioned in the internal cavity. The battery cell assembly includes a frame and a plurality of battery cells arranged in the frame. Each of the battery cells includes a cathode end, an anode end opposite the cathode end, and a body extending between the cathode end and the anode end. A thermistor is disposed on a respective battery cell of the plurality of battery cells. The thermistor is located nearer to the anode end than to the cathode end of the battery cell.
