10000mah 6s $110 "Possible?"
 
Well I was browsing allbattery for the hell of it and stumbled apon some 1250mah 3.7v lipo cells from tenergy. I know that they dont have the greatest rep in the world but just listen. Each cell has 1250mah at 15c cont and supposidly 23-24c bursts. If this is correct the amp ratings will be 18.75a cont and between 28.75-30a bursts. What Im thinking of is ordering 14 cells. 8 cells would be wired in parallel and the other 6 cells will be wired in series to give it a total spec of a 10,000mah 6s lipo with a capability of 15c cont and 23c bursts all for a total of under $110. :surprised: I know its alot of building, soldering & thinking but if someone had the time and patients to do it I think it would be a big reward. Im still pondering if I should take a stab at it.

Heres the cell- http://www.all-battery.com/index.asp...OD&ProdID=2421

And yes I am already aware that the specs will be very different from what were use to seeing here on rcm. The specs would be (64mm x 34.5mm x 84mm). And yes it is taller than it is long.:lol:

Ugg, have fun with that!

Ya it will definately be a pain in the ass to build but a good experience in my opinion and a money saver.

10ma? Where you getting that? Sorry if this is a dumb question but I'm not seeing it. If you have 2p6s of 2000mah cells wouldn't that be 4000mah? (I'm just using 2000mah as an example.

JeffEmbracedDC 09.06.2008 01:44 AM

I'm confused how you would get a 6s 10,000mah pack from only 14 1250mah cells. wouldn't you need 48 cells to do that?

You would need 8 cells in parallel to get 10,000mah and that's only 3.7v.

if you wanted 6s in parellel you would need 6 * 8 = 48 and you'd end up with a 6s8p pack costing you $367.20

am I wrong on this? :/

thought the same thing ^^

it does not make any sence to be. plus it will be one HUGE effin pack.

You're right.

Patrick 09.06.2008 04:06 AM

Yeah you need 48 cells, which would be $367.2 like JeffEmbracedDC said, 1440 grams + all the solder to join 48 cells together, and if you single stacked all the cells it would be 64mm x 34.5mm x 288mm.
Sorry, but it won't work how you want.

t-maxxracer32 09.06.2008 04:10 AM

would be good in theory.

zeropointbug 09.06.2008 04:28 AM

no, in theory it wouldn't work either...lol

JeffEmbracedDC 09.06.2008 06:03 AM

Woot! 3.2 pound battery!

JeffEmbracedDC 09.06.2008 06:12 AM

it'd actually work if you got two of these for $267.80.. http://www.hobbycity.com/hobbycity/s...idProduct=6353 Parallel the two packs in a 6s2p configuration.

it'd be 3.5 lbs (1558 grams).. but at 25c that's discharge rate of 250a :gasp:

Sick.

brushlessboy16 09.06.2008 09:58 AM

or you could just get premade lipos?

Takedown 09.06.2008 11:35 AM

What Im saying is if you ordered 14 cells and wired 8 of them in parallel that would give you 10,000mah and the other 6 would be wired in series to give you the 6s voltage. Im am missing something?
