This is a TQ Wire 1S/2S iCharger Balance Extension Cable. This balance extension is compatible with the iCharger 4010, 308 & 406 Duo chargers and plugs directly into the charger's port and is made for bullet type batteries only. The black lead goes to the negative bullet, the included 2mm tube is soldered to the positive bullet or charge lead. This unit provides use for both 1Cell and 2Cell bullet style packs by "swapping" the 2mm color coded bullets on the cable!
When charging 1 CELL you plug the BLUE bullet to the positive battery bullet (you don't connect the red one). When charging 2 CELL you plug the BLUE bullet to the battery balance port and the RED bullet to the positive battery bullet.
2211 cables now come with a 3-pin plug that requires no cutting to fit in the iCharger 4010, 308 & 406 Duo. When using this updated cable make sure the connector plugs into the right side of the balance port.
