TQ Balance *charger specific* multi-extension cables use our fleXIble triple black 22 gauge cable material to relocate the balance plugs closer to you, making it easier to balance the pack in your car. These cables are made to plug directly into the balance port of your charger. One end has your charger specific plug and the other end has both - XH connectors (SMC, Orion type) and ThunderPower connector. These are 450mm in length and plug directly into the charger and eliminate the balance board. When using the #2207 TP balance extension cable on the new TP820CD make sure the connector on the cable is shifted to the Left side of the charger's balance port. The cable was designed to fit the TP610C that has a shorter port.
