This adapter will wire two of our 3.7V 400mAh Lipos in series for a 7.4V (2S) setup. This type of setup is ideal for many small 3D and park flyer planes because of the batteries' light weight and the huge variety of mounting options afforded by the series adapter.

The adapter features a CSRC/Align/E-Flite-style female balance connector (JST-XH). Combine this with our CSMALE-3V2 adapter for easy connection to your ESC. The male connectors are the same ones used on the Novus series of helicopters.

This adapter can also be used to charge two of the 400mAh batteries in series via the balance connector.

Use with our 3.7V 400mAh 15C or 3.7V 400mAh 20C lipos. We also offer an 11.1V (3S) series adapter for these batteries.
