2 cell lipo vs 3 cell lipo.

[Flatty]

Will I really notice the difference? I am trying to figure out what to run, and I can't figure it out. I am running 8 NI-mh cells on my stock axial ESC for a few months now. I did run 9 cells for a bit. If I run the 2 cell LIPO will I REALLY notice the big difference there? I know it is a 7.1volt VS 11.1volt.

Thanks

um, YES! i run 3 cells and ill never go back. i used to run 8 cell NIMH, and thought it was awesome. when i first tried an 11.1v i thought "no way, too ****in fast!" but now i don't know what i would do without it. my berg 2.2 can do J-turns on smooth floors and pull wheelies on carpet with 45t lathe motors.

yeah I got to second that 3s is the way to go.. just gear down.

Thanks guys. I will be buying my 3 cell this week. Wish me luck with the RTR Axial ESC hahahahahaa

my turck also runs the 3 cell, the 11.1v...lipos are very light...make sure you have some sort of protection voltage cutoff when you use the lipos...you can pick up a novak safety device for like 20 bucks if you esc is not equipped!

flatty,

11.1v is the ONLY thing i will run in my rig. get yourself a sidewinder esc (or a mamba if you have extra cash to burn). i cant believe i ever wasted my time with nimh.

[rockwood330]

i run max amps 3c 11.1 lipos and love them great punch long lasting run times ... wit a sidewinder just set the cutoff and our good to go ...when u go lipo you will never go back ...

[Flatty]

You guys keep takling about a cutoff.... is that the BEC? If so, why is one necessary? What does it prevent?

Thanks

the cutoff is a voltage cut off , if a lipo drops past a certain level, it will not be able to be recharged, some esc's like the mamba max come with a lipo cutoff, novak also sells, a 2 and 3 cell cutoff that can be soldered to your current esc, i use mamba maxs and prefer 3 cell 11v lipos

by discharging your new lipo battery too much you'll destroy it. the cells will puff up and possible explode. you might as well light $50 on fire and stand back.

What would be the difference between these 2 batteries (as far as discharge goes)
http://www.hobbycity.com/hobbycity/s...0C_Lipoly_Pack (30~40C)
http://www.unitedhobbies.com/UNITEDH...00mAh_3S1P_25C (25C constant 30C burst)

Also can you tell me how much runtime the difference will be with these 2?

Also, what kind of BEC would I need on these.

Thanks
Dima

I checked these links and I wood go with the 2100, hands-down! The reviews for the 1000 are not good at all.
Also just for information: BEC = "Battery Eliminator Circuit"
U will need a 3-cell BEC, or one that can handle 11.1vdc.

Where do you guys mount the 3-cell Lipos? Got any pics?

The C discharge rating indicates how much current the battery could dump before blowing up. Most are over rated.

Run time?? the 1400mah will give you about a third more time than the 1000mah. The capacity (fuel level) of a battery is stated in amp-hrs (mah = milli amp hrs) So the 1000mah has 71% of the capacity of the 1400mah. It's like comparing gas tanks, in this case it's like a 20 gal to a 14gal tank, which do you think will give you a longer range with the same engine?

For the Axial on the optional front servo/battery plate.

AreCee- What mah capacity 3S Lipo did you put there? (got a link to the vendor you used?) Some of them look kind of big.

Also, what kind of runtimes do you get with it?

You're right some of them are too big. Go with the 1300 or less. My 1300 just clears the front tire at full lock (increased throw) but the servo ears do contact the left tire. I got the 1300 because the 1000 is the same length but thinner.

I get to do some practice, finish a comp and play afterwards on one charge. About an hour or so, I really don't know because I never ran them until the cutoff kicks in. Comps are five minutes per course!

I would like to see some pics also, I am very new the the crawler scene and need all the good info I can find

[XPLORx4]

AreCee- is this the one you got?
X-Caliber 25C 11.1v 1300mah lipo

No, it's too long 80+mm and too expensive $40.

I bought the one from Value Hobby, it's 3S, 11.1V, 67mm long, 1300mah, 20C and only $20.99 with $3.99 s&h.
