Ok so after much reading is the following an accurate summing up? 1. Voltage drops below a certain figure then it just shuts off to prevent damage to the cells resulting in a crash. 2. Sudden acceleration on a low battery can cause a momentary voltage drop. Again leading to a crash 3. Cold weather will make the problem worse. 4. New update limits power to prevent this happening IF all the above are true wouldn't it be better for DJI to over ride battery shut off?
