Lipo?

[M5burndt]

So i'm thinking about getting one of these, but i'm wondering what the options are as far as battery's. I called traxxas for the dimensions of the battery chamber and they gave me 100x35x20.3 (mm). What 3s lipo's are availiable that will actually fit?

I found some venom 3's 4000 mah on tower but they're way too big.

You need to be looking for mini lipo packs. Duratrax makes a couple 2s option, venom makes a 2s and a 3s pack but by far the best value and performance is the SPC mini packs. $15 for a 2300mah 2s or $24 for a 1600mah 3s. They are a perfect fit in a rally. I have a set of each.

+1 to the SPC lipos.

[rag6]

To the op:
Yes, with spc, you can count on direct first-hand support, and a track record of extreme value. Sometimes paying an extra couple of dollars pays for itself in the end...

[pavmentsurfer]

The first time I ordered my mini lipos from SPC I paid $10 for shipping... but only $23 for the 3S packs themselves. So, I paid only $56 for both packs...

For 2S packs youd pay the same $10 for shipping but only $16 per pack for the 2300mah 2S packs... so your only paying $42 for both of them shipped.

By comparison the cheapest mini packs at tower are the venoms... the 3S packs are only $20... but they are only 1300mah and the 2S packs are $25 and are only 2000mah... Youll pay more for 2S packs from tower even with free shipping than from SPC and youll get less capacity. Youll pay less for venom 3S packs from tower but get less capacity....

I do agree, 3S in a rally is a pretty big waste unless you want to do blistering fast speed runs. I dont even run my 3S packs any more. They are just too fast and create too much heat.

Heres a link to the packs that I think are the best quality and the best value:
SPC 2300mah 2S

I would think Tower has some decent LiPos, but I KNOW SPC does. The prices are extremely competitive, the service is top-notch, shipping is fast and fair. What else would you expect from a team of racers who have a battery company?

Some deals aren't as good as they appear on paper. SPC, however, is the "real deal."

i would get some *****s or *******s they are really cheap and work grate!

but spc make grate packs if you can afford them!

Dont wanna hijack you thread but what doth guys think about Dynamite and SMC lipo's

[pavmentsurfer]

SMC lipos are top of the line... and ive only heard good things about dynamite.. but have never run any.

Im assuming your suggesting 30 minutes of run time out of (2) 1600mah DTX 2S lipos... not one... I run those same batteries and get 30 minutes out of them in parallel.

[CESAR]

Well the LHS has Dynamite 2200mah 25c 2s for $45 and SMC 2200mah 28c 2s for $45

Am leanig thrus the 28c

[pavmentsurfer]

Oh man, no question... id go with the SMC's for sure. But, for that much dough you could get 2 SPC's shipped to your door. The last time Jakey sent me something from SPC it arrived in 3 days. Why pay double for packs just so you can get them from your LHS...

[rag6]

I have 1 dynamite lipo. Works great. Thunderpower lipos, though I have not used them were regarded as top of line race packs at my local track. Idk of any mini packs they sell though.

[CESAR]

I decide not to buy them.

Does 3 more c's make that much difference?

[rag6]

25c-28c? Not really. The spc lipos are 25c x2300 mah= 57.5 amps continuous. The smcs are 28c x2200= 61.6 amps continuous.
Being that this motor/esc will probably not pull anywhere near that amperage, I dont think it will make any difference in performance. for the price, get the spc's.

[pavmentsurfer]

Kinda hard to argue with Jakey isnt it... considering his occupation?

[Jakey]

Hmm, now that you brought it up; today I assembled 4, 1600mAh, 3S matched packs from LiPo cells that I individually graded (tested). For the record, I am "they".

[rag6]

I would like to know how lipos are rated. Is it just a test seeing how many amps it can push in relation to its capacity, or are there other variables that determine c rating?

[rag6]

The 3 packs that you sent me were matched perfectly Jakey, Thanks!

[Jakey]

Repeatable voltage, temperature and capacity parameters at the stated continuous "C".

[Double G]

Best response of the week!!

[rag6]

I vote for :

For the record, I am "they".

Thanks!

[pavmentsurfer]

I wish I was "they"... I just gotta work harder in life I guess...

[rag6]

One more question. Is every cell in the batch rated or just a sample from the batch?

[Jakey]

I can't answer for all cell/pack suppliers, but some test every cell and every pack.

[Jakey]

For the record, I've been "they" for 23 years.

Somehow I seriously doubt that. Otherwise you would not be making such simple, poorly informed statements.

[Jakey]

I wish I was "they"... I just gotta work harder in life I guess...

You are "they" in your field!!!

[rag6]

I think many here doubt it.
