Description of Supernova B54-Battery Pack


Battery Pack for Supernova M99 Mini Pro B54 front light. 

A battery management controller is integrated with the rechargeable battery and enables you to see in the Supernova app the exact remaining light duration for all brightness levels, independent of temperature. The status is displayed on the battery itself with an RGB LED. When there is a sudden change of light, for example when darkness falls or when you pass through a tunnel, the light sensor in the battery automatically switches on the low beam. The optimal charging temperature for a battery is about 20°C. Significantly higher and lower temperatures damage the cell chemistry immensely during the charging process.

That’s why Supernova high-tech battery, like that of a modern electric car, has an integrated battery heater which ensures an optimal charging temperature when it’s too cold. At high temperatures above 40°C degrees, the charging automatically stops until the temperature drops. The polished aluminum casing reflects the sunlight and prevents overheating better than a black plastic casing.
If you are not going to use the battery for a long time, you can put it into Hibernation Mode. It then remains at an optimum voltage on the charger. The Hibernation Mode effectively stops the battery’s chemical aging by preventing a deep discharge.
