Seat Test outcomes: Efest Purple 35A 3700mAh 21700…only 30A however an incredible entertainer, like Golisi S35. Primary concern: This is an extraordinary performing Efest Battery yet it keeps running at near 90°C at its 35A consistent rating. This is excessively hot as I would like to think for tolerable cycle life as most cells say not to surpass 75°C-80°C.
