Internal Battery Pack

Our GLS Platform is so sophisticated that it enables us to produce the longest battery life available anywhere from standard "AA" lithium batteries. The Internal Battery Pack comes standard with the Mobile Terminal and requires one battery pack, which consists of eight "AA" lithium batteries.

External Power Module  and Trailer Tether Sensor


The SkyBitz External Power Module allows you to power the Mobile Terminal from vehicle power when a trailer is tethered to a tractor. The intelligent power system of the Mobile Terminal will automatically revert to its internal battery and your defined power conservation configuration when vehicle power is unavailable.

As an additional feature, the External Power Module will monitor and log when a trailer is tethered or untethered, and it can be configured to electronically alert you of a status change.
