Common Sense RC LiPo Battery 100mAh 20C 3.7V (1S) (2)

These 100mAh batteries are the perfect size, weight and shape for the Estes Proto X, Syncro, and Hubsan Q4 nano quadcopter. They also feature the right connector to make them plug-and-play compatible with the Proto X - that's right, despite what they say 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! These batteries also feature built-in overcharge and overdischarge protection circuits to keep them in optimum condition flight after flight.

Compatible With:
- Estes Proto X
- Syncro
