I dont really see how you will double your amps by running two 2s's

The only real benefit of doing that is to distribute the weight evenly over the chassis, and the extra benefit is if you have other cars that use 2s you can use them for your other cars as well.

If you mean amps as in amp draw/c rating it's the same for both 2s2p and
4s1p. Running 2 "standard" 2s packs together to get 14.8 volts won't increase your amp rating.

no im saying if i buy 2 5000mah 2s 40c lipos i will have a setup running 5000mah at 14.8v with 40c.
if i buy 2 5000mah 2s2p 40c lipos i will have 10000mah at 14.7v with 40c.
is this correct?

No, it's still a 5000mAh. P doesn't work in the way you are asking, assuming equal overall size batteries.

slash24

then can you explain to me what the p rating does on a lipo?

Dave H

In the case you are asking about, it allows the manufacture to make different capacity packs with the same cells (and tooling, etc for same). The 5000mAh 2S2P is made up of 4 cells, each of 2500mAh capacity.

For most practical intents and purposes, a 5000mAh 2S1P is essentially the same as a 5000mAh 2S2P. The first is made of two 5000 cells, the second is made of four 2500 cells.

Putting two identical cells (or batteries) in parallel does increase capacity, but also is twice as big (& heavy). Two 5000mAh 2S1P put in parallel would make a 10000mAh 2S2P, at twice the size.

Understand it can be kinda confusing, hope this is at least somewhat clear.

oh ok i got it now. i was looking at it the wrong way. ok thanks
