<FONT face="Tahoma, Arial, Helvetica, sans-serif">I have been using the ETEK motor for a peirod of three years in proto type usage. I am using it as a 36 volt system with 500 amp batteries and have not had any problems with it . I am pulling 65 amp draw with the motor loaded on the mower and only 20 amps with it riding the mower. If any one has had trouble with the unit I would like to know. There is many uses for the motor at present. I have seen it on a motorcycle at 24 volts . It has been on a boat using as a inboard and also has been on a drag rail car with 48 volts . </FONT>
