Default Mamba max ESC and BL questions

Hey I did some trading last nite and got ahold of a XXXT MF2 with Mamba max and BL 7700 KV......The fellow I traded with gave me 2 NiMH 7.2 V 2000mah Batteries.....after doing some research I discovered that this motor calls for 8 cell vs. 6 cell....or Lipo....and since I dont have Lipo, and this is my first Electric Im not sure if it will just be slower with the 6 cell or will it damage to either ESC or Motor.....just for now!.....Ill get lipo eventually but I really cant afford $200 charger right now.....and again old nitro guy here when I wire it all up dont I have to have a connection to the batt. plug on the radio or does ESC bypass that somehow?
this has been the best site for help in my nitros onroad and hope itll be the same here!
Thanks again!

will be just fine on 6 cells i run my mm5700 in a zx-5 sp with 6 cells. i would suggest getting batteries with more mah, like 4200 or atleast 3300 or 3800. the esc will run on more but dont need more, more cells is just more speed. a 7700 on 6 cells is goin to be very very fast. most 1/10 eps run on 6 cells it is the norm, i think the mm esc can handle more though.

I think you'll be fine. Your run time is going to be pretty short though. Keep a close eye on temps, not because of the battery, but because of the motor. And honestly, if you're going to keep that motor, don't spend too much on batteries because it's going to be insanely fast with a highend pack. There was a noob at my local track with a 7700 but his packs were cheap stick packs and it didn't feel any faster than a 4600.

the only problem with cheap packs is cogging have to have good batterys for brushless not lipo but good qulity batterys

so in summary it will not harm the ESC or the Motor to run 7.2v packs in this setup....what about the battery input on the radio.....do I need splice?
