The Panasonic NCR18650B cell is designed for maximum endurance (capacity), not for high current. In addition, the protection circuit (PCB) limits the maximum discharge current to approx. 5 to 6 amperes. Modern sub-ohm e-cigarettes, however, often require short-term peak currents of 20A to 30A. The ECELL battery would immediately shut off due to the protection circuit. For e-cigarettes, use special, unprotected high current cells (e.g. Sony Konion VTC5/VTC6).Does the battery fit as a replacement for the battery in my laptop or e-bike?No. In laptop battery packs, e-bike batteries or power tools, unprotected industrial cells (Flat Top) are firmly welded together. The battery management is handled by a central external board for the entire pack. A single, already internally protected cell with Button Top cannot be welded into such packs and would interfere with the external system.Why does it say 3.6V on the battery when my charger charges up to 4.2V?This is completely normal. 3.6 Volt (or 3.7 Volt) is only the nominal voltage, i.e. the average operating voltage over the entire discharge cycle. When the lithium battery is fully charged to 100%, its actual voltage (final charging voltage) is exactly 4.2 Volt. If it falls to approx. 2.5V to 3.0V, it is considered empty.

It is determined by the height of the pictogram and is specified in the EN 1838 standard. A detection range of 27 metres is a common standard value for many areas of application.Why is a pictogram set included?A separate set offers maximum flexibility on the construction site. The final direction of the escape routes is often only clear during installation. With this set, the installer can individually adapt each luminaire to the conditions without having to carry different luminaire variants with permanently printed pictograms.What is the blank film used for?The blank film (or dummy film) serves as a placeholder or can be used to cover one side of a luminaire if required. In some cases, it is also used as a pure signal luminaire without a specific direction to generally mark an emergency exit.Can the luminaire be operated in continuous and standby mode?Yes, depending on the version, the luminaire is designed for both operating modes. With single-battery luminaires, this can often be set directly on the luminaire. For luminaires for central battery systems, the operating mode (continuous operation/DS or standby mode/BS) is set centrally in the emergency power system for the respective circuit. According to most building regulations, escape sign luminaires must be operated in continuous operation.
