    PRODUCT EVENT SUMMARY: THE CONTROLLER WAS RETURNED FOR EVALUATION AND SIX (6) BATTERIES WERE NOT RETURNED FOR EVALUATION. FAILURE ANALYSIS OF THE RETURNED CONTROLLER REVEALED THAT THE DEVICE PASSED VISUAL EXAMINATION AND FUNCTIONAL TESTING. LOG FILE ANALYSIS REVEALED THAT THE CONTROLLER IN USE DURING THE REPORTED EVENT CONTAINED A FEATURE THAT RECORDS WHETHER A POWER SOURCE EXPERIENCED A COMMUNICATION ERROR OR A DISCONNECTION WITHIN EACH 15-MINUTE INTERVAL. ANALYSIS OF THE DATA LOG FILES REVEALED ONE PREMATURE POWER SWITCHING EVENT THAT WAS DUE TO MOMENTARY DISCONNECTION INVOLVING ONE BATTERY. AS A RESULT, THE REPORTED POWER SWITCHING EVENT WAS CONFIRMED. LOG FILE ANALYSIS ALSO REVEALED ONE (1) CONTROLLER POWER UP AND ASSOCIATED MOTOR START EVENT. THE DATA POINT LOGGED ON THE CONTROLLER'S INTERNAL LOGS PRIOR TO THE CONTROLLER POWER UP, REVEALED THAT ONE BATTERY WAS CONNECTED TO POWER PORT 1 WITH 51% RELATIVE STATE OF CHARGE (RSOC) AND ONE BATTERY WAS CONNECTED TO POWER PORT 2 WITH 21% RSOC. THE CONTROLLER WAS WITHOUT POWER FOR 12 SECONDS. AS A RESULT, THE REPORTED POWER LOSS EVENT WAS CONFIRMED. A POSSIBLE ROOT CAUSE OF THE LOSSES OF POWER CAN BE ATTRIBUTED TO A DISCONNECTION OF BOTH POWER SOURCES AND/OR TO AN INTERMITTENT DISCONNECTION ON ONE OR BOTH POWER SOURCES. THE MOST LIKELY ROOT CAUSE OF THE REPORTED POWER SWITCHING EVENT CAN BE ATTRIBUTED TO MOMENTARY DISCONNECTIONS. AN INTERNAL INVESTIGATION WAS INITIATED TO EVALUATE MOMENTARY DISCONNECTIONS. AN INTERNAL INVESTIGATION WAS INITIATED TO CAPTURE EVENTS INVOLVING THE CONTROLLER LOSING POWER. ADDITIONAL PRODUCTS: BATTERY (B)(4).
