Support@Seestar After further investigation I see that the battery in the Seestar has 3 wires which means that one is connected to a thermistor, i.e. temperature sensor, attached to the battery. So the Seestar software is clearly designed to look at the feedback from the thermistor to decide if the temperature of the battery is within the safe charging range, 0C to 40C. If not, the battery will not charge. So the Seestar at least provides low and high temp charge protection. The low temp protects against loss of capacity and the high temp protection protects against catastrophic damage to the battery, i.e. fire. Most likely why the Seestar forces a shutdown at 60C.
