No, cell phones use lithium-ion batteries and model airplanes use lithium-polymer batteries.
To put it simply, the discharge current of the cell phone battery does not cannot meet the requirements of excessive current discharge. will cause the battery to overheat or even cause a car accident. Danger
The advantage of lithium polymer batteries is that the internal resistance is very low and can withstand continuous high current discharge
Think of a small F3P aircraft with a current about 5—— 8A, can a cell phone normally discharge like that? Haha~
