Yes, there is an indicator on the internal battery powering the wireless hand controller. Though much testing, we have found this indicator can be misleading. When plugged into a charger, the indicator flashes red. If the battery is very low, the battery is charging but at a very very low charge rate. The protection circuitry may be monitoring the very low battery level and will trickle charge at best. The flashing red does not necessarily mean the battery is being charged.
The indicator changes color as the battery charge level increases but is inconsistent from battery to battery. The color change sometimes occurs as low as 50% and sometimes as high as 80%, So the indicator does not aid in determining the charge level of the battery.
One of the functions of the wireless hand controller is the Hold-Black-Button-Press-White-Release. This will take a reading of the actual battery charge level and output the level to a Track Safety Light or Safety Cube. The TSL displays a very accurate charge level reading when compared to the indicator on the battery. As the battery level changes, the TSL will display and change from red to yellow to green to indicate the battery charge capacity.
