Up-lighters will be supplied in purpose-built flight cases of 6 units, complete with inbuilt charging station. The cases can be directly connected to the mains, and an intelligent auto-charging function means they can be stored connected for several weeks and always be ready for action.  In order to ensure longest life time of the accumulator, we have developed sophisticated software control of the charging station embedded in the flight case. The charger checks on accumulator capacity and voltage as well as on some other parameters like times between charges in order to indicate and ensure best charging procedure for each accumulator.
