Lipo cutoff for Novak HV-MAXX?

[JAILBIRD]

I just picked up an E-MAXX with the older Novak HV-MAXX BL system. I got the instructions on line and found out there is no lipo cutoff built in. The cutoff that origionaly came with the system is missing. What do I need for a replacement? The batts I"ll be running are 2 2s Enerland 5100mah 25c packs.

Also, is the sensor cable replaceable? there is a plug on the ESC but not on the motor. The cable I have has some repairs done to it so I'd like to replace it. Thanks for any help!
