Description
20 cm JST-XH balance extension
This balance extension adds 20 cm to the JST-XH balance lead of your LiPo batteries. It has a male plug on one end and a female on the other, with flexible, heat-resistant 22 AWG silicone wire. Choose the 4S or 6S version.
It is handy when the charger sits away from the charging bag, when the battery’s balance lead is short, or to avoid wearing out the battery’s own plug by plugging it in and out many times.
With the balance extension you can also leave the lead plugged permanently into a parallel charging board or your charger and connect only the batteries, so the wear falls on a cheap cable rather than on each battery’s plug. Check now and then that the pins seat firmly with no play.
