This is connector saver provides a bigger grip. Added onto your LiPO's JST-XH balance connector, it allows you to more safely plug and un-plug the balance connector from your charger.
Can be taken off from a balance connector and reused on another battery.
Because of different width, this connector saver will only work for a 2S JST-XH balance connector, commonly used on Hobbyking, GForce, E-Flite brand LiPOs.
Does not work for Thunder Power LiPOs, or batteries that don't use JST-XH type connectors.
