i know that this has been covered many times but i just need a good clarification and explanation. ok so you have the number of cells in series in a lipo (s).

then you have the cells in parallel (p).

so for example if i have a 5000mah 2s 40c lipo it would be 7.4v
and if i had the same battery but as a 2s2p setup this would give me 10000mah? correct??
so i would have the same amount of output from that battery but a longer duration...

so really if im going to buy a battery it might as well be a 2s2p instead of just 2s right?

well... yes but that battery would be big and heavy, really depends on what your putting it in, what i basically do is get the biggest mha rating that will comfortably fit in what ever I'm putting it in

not 100% true thunder, a 2s2p pack could be made with 4 small cells vs. the 2 big cells that most 2s1p packs have in them and be almost or the same size and weight. With current lipo tech. it's just not the best way to do it though.

Assuming 5000mah in both

Slash, what are you looking to use this battery for?? To get the 10000mah rating your looking at it would be about the same size as a current 4s pack just wired different internaly

slash24

well i have a 2wd slash. and as many people know i did a little project recently and i put a mamba monster 2200 in it. so thats the truck and motor/esc i would be running it in. my suspension is beefed up to accompany the weight from the motor.

oh, yeah, i was thinking he would have 2 2s batterys with a paralel harness, like a e revo, but yeah if its just one battery then it wouldn't be as big i was thinking

A 2200 kv rated motor on 7.4v is gonna be dog slow. That motor was desighned for 1/8th scale running on 4s..

iTrader: (31)

You're right on that part and that was my first thought but it's not the only possability.. 10000mah 2s2p 7.4v would be twice the size of a 2s1p 5000mah 7.4v pack

slash24

well yeah i know that i was just using that battery as an example. but yeah i was planning to run a 4s and 6s setup on it. so what do you think run 2 2s packs or 1 4s pack and make it 4s2p or 1p... thats the question. what is going to benefit my setup?

racer1812

iTrader: (31)

both would be 14.8v, the 4s2p would simply have 8 smaller cells vs 4 bigger ones. 1 4s1p pack for the win.

Rather than trying to make two batteries fit, why not just buy two 4s1p cells and run one after the other? It seem to me that your concerned with runtime. Trying to make 2 4s packs fit will be difficult. Just find your self a 5Ah 30c 4s Lipo. I think you'll be plenty satisfied with the runtime. You can always buy a second when the first one runs out.

well im not really all that concerned about the runtime. i was just wondering if i would loose anything by getting the 2p over 1p. so really runtime isnt my big concern.

racer1812

might be easier to find a 1p that will fit vs. the 2p. I don't see any gain from a 2p pack though, why not just get the 4s1p?

slash24

well i can fit two batteries side by side if i put them in the tray vertical and buy a modified battery bar. so i would double my amps and still have my 14.8 volts by running the two 2s2p rather than one 4s1p.

slash24

thats really just how im looking at it. does that sound right or does anybody think otherwise that this would not do me any good?
