The fit between the battery boxes and the frame was not 100% so I had to seal the spaces with sealant. As can be seen in the image below the shields of the battery cables are now grounded to the battery box. All battery and motor cables are shielded to reduce the electromagnetic radiation that appears due to the motor controller.The light grey cable in the middle is the thermistor that senses the battery temperature. The charger uses this information to stop charging if the temperature goes below freezing.
