maxxamps
 
Ok guys. so i found this on maxxamps. MaxAmps Lipoly 8000mah 3S2P 11.1V Pack $159.99

Is this one pack or two? I thought the 2p meant two packs? this looks like one.
I've also been pondering on getting the 12020 controller. Would it handle 3s2p 8000mah? What volts should I get with Lipo with this controller? If I don't go 3s2p, i'll go one 3s and one 2s in series wiring. Am I on the right track? thanks! i want to run two packs in series...thanks!

yep thats one pack the p stands for cells in parallel. that controller will be fine you will just need a lvc (low voltage cutoff) for your lipos. i take it your wonting to run 5s (18.5 volts) in your truck? if so you'll need that pack plus a 8000mah 2s2p pack an run them in series. hope that makes sense :025:

A little. I guess what's confusing is the lingo. Squee suggested i run 5s , one 3s, one 2s at 8000. So what he meant was one 3s2p 4000 mah, and one 2s2p 4000mah = 5s2p 8000 in series wiring? is that right? Now, how do i configure the volts? Amps? Fpr some reason i thought series wiring only doubled the volts? IE: 7.2 x 2 in series = 14.4.

if you went with 4000mah packs and wonted to run them in series (positive to negitive) you would still end up with 4000mah the mah only increses if you run the packs in parallel (positive to positive). i would suggest running 1 3s2p6000mah pack and 1 2s2p6000mah pack wire them in series (positive to negitive) to get a 5s pack. series does only dubble the volts. in your case its 11.1 of the 3s pack and 7.4 of the 2s pack, wire them in series to get 18.5 volts

Ok, i get it! Taht would work with my 9920 wouldn't it! The 6000 mah wise i mean would work with the 9920?

Chaos 06.29.2006 04:13 PM

why not just get the 5s3p 6600mah pack and not have to worry about wiring? 18.5v 90a 820g $261, or am I missing something, cause I plan on running this pack, only the 4400mah

neweuser 06.29.2006 04:21 PM

The one pack 5s2p? My 9920 is already in series wiring. So my end thoughts...12020: one 3s2p 8000, one 2s2p 8000, in series. Or 9920: one 3s2p 6000mah, one 2s2p 6000 in series. Both of these set ups would work with a 10xl BK?

Chaos 06.29.2006 04:46 PM

no maxamps has a 5s3p 6600 mah that I am talking about, but you're already wired for 2 packs so that's cool, I am wanting to use only 1 pack that is why I am looking at this pack

coolhandcountry 06.29.2006 06:04 PM

If you run one pack all your weight is going to be on one side unless you have a truck with it mounted in the center. The 9920 can run on 6s lipo as well.

squeeforever 06.29.2006 06:04 PM

HOLD ON GUYS.... Newuser, first off, the only difference in the 9920 and the 12020 is how many amps it is capable of delievering to the motor. A 9920 is PLENTY for a 10XL. No need to get a 12020. Also, I would recommend either 5S LiPo or 6S LiPo. 6S is about like 20 cells and 5S is about like 16. I'm running a 10XL as well and going with 6S LiPo. It just depends on how fast you want to go. Now, as for batteries. Get 2 packs and not one because it balances out the weight evenly. Chaos, one reason not to get the 5S3P is because thats 15 cells! a 5S2P 8000mah would be better and only 10 cells. Stampy has it right as well. Series only doubles the voltage. Parallel doubles mah and amp draw but not voltage. I would run series because usually parallel will be more expensive. Newuser, go with 2 3S2P packs or 1 3S2P pack and 1 2S2P pack in series for 5S2P. Understand? Lastly, the 9920 can handle ANY mah as well. No worries about that.

Chaos 06.29.2006 06:11 PM

well you say no due to it being 15 cells, but what is the difference when it still comes to 18.5 volts and plenty of amps? and I think the balance will work since the motor is offset, and I will put the controller and receiver where the other battery goes. Not trying to argue, just trying to get it sorted out::028:

squeeforever 06.29.2006 06:14 PM

15 cells is alot! That pack much be HUGE. I personally don't think that the motor, controller, servo, and rec. way as much as that pack. Probably like half...

Chaos 06.29.2006 06:18 PM

the 5s3p is 820 grams, the 5s2p(which I will run) is 543 grams, a standard 7 cell pack is 560 grams

squeeforever 06.29.2006 06:20 PM

Yea, I would stick with the 5S2P if your heart is set on a 1 pack setup.

Chaos 06.29.2006 06:24 PM

not totally, but for the price and the maintenace, I could have 1 pack and run about the same as if I had 2, plus I would only have to charge 1 and run 1, am I wishfully thinking or will this work just fine it's just not the norm?
