USB Battery Charging
You can charge the batteries while they're inserted in the grip by using the Micro-USB port. Use your camera's cable to
plug it into a USB power source. The charging status LED is red when charging, and green when charging is complete.
Battery Status
When two batteries are installed in the BG-S4-2, your camera will automatically select the battery with less power
remaining. The battery level will appear on your camera's LCD with the battery level percentage for only the battery
in use. When the battery is depleted, your camera will switch to the other battery in the grip.
