The majority of lithium polymer batteries used in radio control come with JST-XH balance leads - you can use this 30cm extension cable to give you more length to put the batteries inside a lipo sack while charging. These adapters improve on the original by replacing standard 22 (or even 26) awg wire with the biggest that can be used with JST-XH, 20awg wire made up of 100-strands for optimum electron flow!

This listing is for (1) 30CM (~12in) 3S JST-XH Balance Tap Extension Adapter with 20awg Red / Black Wire - 1 Side Male / 1 Side Female.
