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.

thats what I thought.....heres the thing thats got me puzzled when you go online on http://www.castlecreations.com/products/mamba_max.html
on the right under tech specs!! check it out... BIG RED LETTERS

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.

yea there talking about the emaxx or things like that u have a mf2 correct thats a 2wd staduim truck

rjs_13203

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

indeed it is a 2wd Stadium truck......

rjs_13203

they are talking aabout not running them in monster trucks such as the emaxx

what is cogging?

rjs_13203

will like stutter on the start sometimes a little sometimes real bad. if u have the mm esc u can change the throttle curve and it will be fine

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?

rjs_13203

iTrader: (5)

splice? just run it like it was a brushed system but no need to mess with the motor. plug and play

rjs_13203

oh u should be able to plug the esc into the receiver and be all good, though u might have to buy a better radio if its am cuz the brushless can interfer with the radio

I plan on using JR RS 300.

should be fine just keep receiver away from the motor wire it can pick up interference.
