I have decided to consider using a new 48v contactor. The current coil in the contactor is rate 12-36v… so it is being stressed because the Kelly Controller asks that the contactor be connected through the 48v battery. So to amend this moving forward I have a more appropriate 48v connector that will take 200amps.

To increase the efficiency of the system further I will move the location of the controller up to the top enclosure (probably in the switch panel so that there are less cables running up and down the bike and less opportunity for voltage drop due to distance).
