This charge cable made by RC Accessory allows the e-Station BC-6, BC6-10, PB-6 balancer and Two Meter products to balance charge the hard case lipo batteries by Trackpower, Orion, and Checkpoint. For the BC6-10, an 4mm bullet extension cable is required to lengthen the power input leads since the BC6-10's power output is on the opposite end of the charger from where the balance port is located. Made from gold plated bullets & 14 AWG wire. Power ends are standard 4mm bullets and the balance lead is 2mm bullet.
