If you want to go 24 cells, the 10XL would be my motorchoice..

TRUST ME MACK!!!! 20 IS MORE THAN ENOUGH!!!

It really is.. you never ever drove a truck with that much power. try it on 16 or 18, with the 2speed transmission. on 18 it will be so fast, it can do circles around your nitro savage...

If you have never ran a bl system. I hope you have some good equipment. It is hard to drive a truck at 55 mph. Just let us know which way you go. I think the 10xl is better for a 24 cell count to run. more run time to.

Okay i had another chat wiht SERUM on the email
So now he defently convinst me.
I will go whit the 9920 and the 9XL

[coolhandcountry]

I think you will like it. I has some good power and run time. for the money it is a great system.

[mack]

Yeah I think so.
And my friend SERUM has got a nice deal for me for the controller and Ubec.
And because this will be my first BL setup,
he will sepports me on email.

"SERUM YOUR THE BEST THANKS"

Ýeah Mack! no problem..

No need to scream it in my ear.. ;)

[mack]

Okay serum but you have been a great help for me.

I am curious tho if i want to push the limits.
Can I put 7s on the 9920 I now its say's max 20 cells of 1.2v so max 24.
put will the controller handel the abuse.

[Sneeck]

7s will be over that limit. 6s will be insane allready.(which is 22,2 volt's) Why on earth you want maximum power and speed while you haven't even driven brushless yet?

Trust me, you'll love the 9920 and 9xl.

Kind of odd thing to ask, but anyone have experience running a 9xl and 6s lipo? I mean, just how nutso are we talking here? I saw a vid of a Savage with a 8xl and 6s, but would think the 9xl is a bit slower........which might be a good thing, that 8xl was flat out stupid.

It will be just a tad bit slower than the 8XL, and you'll get more runtime. I don't really think an 8XL on 6s is too nutso, it depends on what you really call nutso I guess! :L: I do have a 10XL and 18 cells in my Savage right now, and once I finally recieve my spurs I'll tell you how it performs.

I now it's over the limit, but normaly its just to be safe so I thought maby a bit more than 24v would work.
7s will be 25.9v 6s will be 22.2v
So 20 cells (24v) wil be faster than 6s?(top speed)

I'am just starting on 16 cells
But i'am just CURIOS if it's possible.

Coolhand runs his 9XL with up to 18 cells, thats as close to 6s as i've seen with a 9XL

[coolhandcountry]

there is a video in the webiste I have started at rcpics . It has the 9xl on 16 cells. I can not test the 9xl no more on hi cell count until I finish my truck or get a new chassis. I would like to test the 9xl on 20 cells but do not have the limits. I am scared to try it on a 7020.

Fully charged, a 7s Lipo is 29.4v. Lipos won't drop their voltage much after a charge unless you don't let the CV phase get to completion. 6s fully charged is 25.2v. 20 NiMh cells fully charged (about 10mins. or so after charge finishes) will be at about 27v.

[mack]

Allright MetalMan but still there is the question will
the 9920 survive 7s so the 29.4v what do you think?
