OK, so yeah it's got two male Dean's plugs in series. So all you would need to get is a female Dean's plug and a small piece of 10G or 12G wire. Solder the wire across the two tabs on the female Dean's (use a little bit of heatshrink to ensure there is no exposed metal). Then you plug your newly made jumper into one of the male plugs on the ESC and plug your battery into the other one. All set to use a single battery, and if you decide to use two batteries you just remove the jumper.
