Got a slight issue with my LRP speedo, i have the lipo cut off / temp cut off set for 2S lipos. I turn the car on and it will be fine for about 20 seconds then the lights flash and car cuts out

, i checked the status of the lights and its a temperature cut off. How can this be when the car is stone cold? I have removed the lipo cut off and the car is fine, im just a bit nervous running it with out it turned on! anyone got any ideas?
