COMMON SENSE RC Lectron Pro 3.7V 450mAh 30C Li-Po Battery with Walkera Connector

This 3.7V 450mAh 30C lithium polymer (lipo) battery was designed specifically to be a perfect fit for all versions of the Hubsan X4 quadcopter, Dromida Kodo and Dromida Verso. That includes the H107L, H107C camera version, H107D FPV version and many others. These batteries are a drop-in replacement in all the quadcopters listed above, no modifications necessary. They also include the correct Walkera-type connector for both the X4 and the Kodo plus an integrated overcharge protection circuit, so they're completely plug-and-play compatible with both quads and the chargers that come included with them. The 450mAh capacity means you'll get nearly 20% more flight time than the standard 380-390mah batteries for these quads and the 30C discharge rate means this battery will be able to provide that extra boost of power when you need it most.
