lipos for my emaxx
 

I need some lipos have NO idea what i am looking for. here are my specs
20120 speed control
10xl motor (or bigger i am buying a new one soon)
8 spider diffs
single speed with steel idler

It depends on if your looking for runtime or speed. How long do you need to run?

a tad of both. i want 30 minute run times minimum

I would say 8000mah 6S lipo would be awesome. And probably over an hour runtime.

OMFG. what kind of speed should i be getting? and exactlly what motor should i get ( cannot spend alot on my motor)

also how long do lipos last. if i charge and discharge and all of that. what should be the life on these?

I would say 55+ on 6S lipo with the 10XL. It really depends on exactly how well you take care of them. BTW, you don't discharge LiPo's like NiCad.

if i followed by the book instructions on how to take care of them?

It would depend on MANY things. How fast you charge then, how often you balance them, ect. And the biggest....the QUALITY of the cells. Theres really no telling. However, I would say, a couple hundred +

what batteries should i purchase than. from what company and all of that?

Is that 6s2p in series? or just one 6s? Just curious...

I would recommend 2 3S2P in series.

do i need to wire them myself? i am not good with that kind of stuff. only soldering plugs lol!

Actually, if you can solder plugs, wires are easier, just make sure you tin them before soldering together. someone here should be able to direct you to a wiring diagram....if your talking about batt packs, you should be able to choose preassembled packs or loose cells....

Ok, is this the 3s2p that would work? 11.1 volts 159.99? http://www.maxamps.com/index.html?la...d=38892.783403 Is this the price for two packs?

Obviously, i would need a new controller because i run the 9920, like maybe 12020?

Why would you need a new controller?!?!? and thats for one pack. the 2P means that there are 3 groups in series of 2 cells in parallel.

You would need two of those packs.

I guess i thought i would since the burst is at 128 amps. the 9920 is only at 95 amp rating. but, i may not totally understand all that. So if i ran one 3s2p and one 2s2p at 8000 mah with the 9920 that would work? Making it a 5s lipo 8000 mah?

Yes, that would work. Don't try to correlate the battery's amp-handling capabilities and the 9920's amp-handling capabilities, they have nothing to do with each other. What you do need to work with is the motor that you're using.

I have the 10xl wanderer...As the other thread i started, here is my end thought....one 3s2p 8000mah, one 2s2p 8000 mah bringing me to i think 18.5 volts in series wiring and balancing my truck. So, here would be my set up: 9920/10xl with 5s 8000mah lipo with UE diffs and 40 series tire. what speeds would i be looking at?

About 52. About 59 on 6S LiPo

Ok. The reason i ask is because I have the UE diffs. And after putting those in, my truck seemed considerbly slower. I'm assuming because the gear ratio changed (duh). So I bumped up my pinion to an 18T. I ran again last night(second run), It still seemed REAL torquey(if that's a word), but added some speed. My temps are still down pretty good so I'm gonna try the 20T I have tonight and see what that does. FYI 20T/51 spur. Does Ofna make a smaller spur that I could use with the strobe slipper to add more speed if I wanted to try that? But this is without the LIPO, 16 ib3800's. thanks for all the help guys!
Squee: When did you become a MOD?

I think Mike might be able to get you a bigger pinion if need be. And no, there aren't any more spurs :frown:. Oh, and I've been a mod for about 2 months :p.

For some reason, i never noticed until last week, just never asked i guess! Great JOB! Thanks for all your help on LIPO once again! I think i may have a pretty good grip now!

No problemo man!
