I have a project that consumes a max current of 1.6A, that requires the use of a small LiPo Battery. I have one that has the perfect size, but has capacity of 400mA, and a discharge rating of 1C (400mA max). I understand that the internal resistance of a battery is what causes them to heat up under heavy current draw, but would battery thermals be the only risk when drawing 1.6A from a 400mA LiPo battery?
