Look at the 2 pics on the links you posted, the battery leads can be soldered directly to the ESC just snip off the balance leads (the 3 smaller wires) and save.
Your charger will come with charge leads but not generally balance leads, if you have bought 2 or more batteries then you will have balance charge leads that can be spliced into charger leads possibly without connectors or with deans or 4mm banana
