These 100mAh batteries are the perfect size, weight and shape for the Estes Proto X / Syncro X / Hubsan Q4 nano quadcopter. They also feature the right connector to make them plug-and-play compatible with the Proto X / Syncro X -- that s right, despite what the manufacturer says about the Proto X s battery not being replaceable, our battery is designed to plug directly into the quad s main board, no soldering or adapters required. Also, the canopy will fit the same way it does with your stock battery!
Flight Time Per Battery: 3.5 to 4 minutes
