The Zacuto Gripper Series GR-100 Clip-On Battery is a lightweight battery that attaches directly to 15mm rods. Because the body of the gripper battery is able to clamp onto your 15mm rods, you do not need any additional mounting accessories when using this Gripper 100 W/h battery, which helps you save space on your rig. The battery comes with two P-tap outputs (one in front and one in back), and you always have the option of increasing the number of P-taps if you were to use a Gripper P-tap adapter. The 14.4v battery has an LED fuel gauge on the side, which keeps you informed of the remaining capacity of the battery. This battery is ideal for the traveling photogropher or videographer, because each battery has been UN tested for airline safety. It is perfectly suitable as carry-on luggage during your travels.
