Tx lipo balance connection with charger

[brown4s]

I have purchased a VOLTZ 2300MAH 2S 7.4V RX LIPO STRAIGHT BATTERY PACK

I have an LRP touch competition charger which has the integrated balancer connection which is an EHR connection.

My problem is the connection on the volts lipo does not fit into the ehr connection.

Do I not balance charge this lipo or what do I need to get it connected through my charger via the ehr connection on the charger ?

Some advice would be appreciated
