As the X5 Power System can be formed of two X5 Hot-Swappable Batteries, as well as an internal hold-up battery, a state-of-charge indicator was designed to show the status of each connected battery in one convenient place.

Called “The Track”, due to two state-of-charge indicator bars that meet to form a race track type shape, the pendant displays remaining battery life in runtime (hours/ minutes) and percentages.

An RJ45 female connector allows “The Track” to be easily connected or disconnected from the power system. Any charging errors are shown on the pendant’s 2.4in display (with full glass front). The display contains an adjustable backlight and night light to help with 24/7 usage.
