Under normal operation, the lights will glow solid white. When the battery is low (under 30% battery), the lights will glow yellow. When the battery is in this yellow state, the ARENA may still be used but should be charged soon. When the battery is critically low (under 5% battery), the lights will change to solid red and cable force will slowly be faded down to 0 lbs over the period of about 30 seconds. Battery status will be shown in the ARENA app as well; monitoring of the ARENA lights is not required for operation.
The battery may last up to 30 days on a single charge, depending upon usage. Charging takes around 3 hours for a full charge.
