The Spektrum™ Balance Extensions, with their 24-inch-long charge and balance extensions, are designed to extend the JST-XH style balance plug on a LiPo battery for charging purposes. For hobbyists who want more flexibility on where they want to charge their batteries, such as in a LiPo bag, these extensions are the perfect solution. They include a normal balance lead for Spektrum G1 Smart or competitors' batteries, and a grey Smart wire for use with SPM G2 Smart batteries, ensuring a secure and efficient charging process.
