Looks incorrectly wired. Thermistor should be connected to contacts on under side of battery pack and red and black wires T end connectors I believe red is positive. 
While probably not safe without the temperature fuse, if battery’s are in series it should work. I’m not sure how the ends of the batteries opposite of the contacts were connected. When I’ve rebuilt a battery pack I used tabbed batteries and soldered the connections. I used existing “temperature fuse”, not actually a fuse. 
See Frank’s site for images.
