The battery may not be the best but there's no reason for it to go until it's useful life is done. It should be more than adequate in a 2WD SC truck.Gearing to high means either the spur is to small or the pinion is to big, both result in higher gearing. I would use a temperature gun first and check the temp because 150 is safe but will still feel pretty hot.
