Never mind, after more research, I remembered that Lipo's need a low voltage cut off. so I will have to use new nimih batteries.
You can buy a LVC and then you can use lipos with the stock esc.
+1, or you can also grab a couple alarms instead of cutoffs like [link=http://www.ebay.com/itm/1-8S-Lipo-Battery-Tester-Low-Voltage-Buzzer-Alarm-RC-1S-/320669324354?pt=Radio_Control_Parts_Accessories&hash=item4aa9619442]these[/link] and a couple 2s lipos and you're ready to rip.
I like the alarms better because they monitor each cells voltage, instead of an ESCs built in cutoff since it only knows total pack voltage.
