The Sennheiser L 2015 (article 009828) is a quick-charging unit for two Sennheiser BA 2015 rechargeable battery packs. It is used by rental companies, theatres, churches, schools and presenters running Sennheiser bodypack systems, and saves the running cost of disposable AA batteries. The BA 2015 packs can be charged either on their own or while still fitted inside compatible bodypack transmitters and receivers: evolution wireless G3 100, 300 and 500 series, the 2000 series, and Tourguide SK 2020-D and EK 1039. Charging is automatic, with charge and ready indicators for each of the two bays. Several L 2015 units can be daisy-chained and run from a single power supply, which keeps a charging station tidy when many packs are in use. Note that this SKU does not include a power supply unit or batteries - order the correct Sennheiser PSU and BA 2015 packs separately. The unit measures roughly 147 x 122 x 90 mm and weighs about 370 g.
