What is the difference 2s 1p or 2s 2p ?

[lenny]

Looking to by lipos, not shore what to by.

2P or not 2P ...


All kidding aside a 2S2P is like having two 2S1P in parallel and doubles the mah. So if 1P is 5000 mah than a 2P will be 10000 mah.

So what is better for long sport running ? A 2s 1p 30c 5400mah or 2s 2p 30c 5400mah

Thank for input.

They are the same as far as power goes.

If you are only running 2S (7.4V), you buy TWO 2S 5400 packs and wire them in parallel. That gives you 10,800mAh. That is what you want for long running. The same goes for running 3S or 4S, etc., parallel two packs to double the mAh. The mAh determines the run time.

OK ! than way do they make 1p and 2p ?
Feeling (dum) hear, Need to know. New to fe.
I have two boats a rio ep stock for now, looking to go brushless soon 1 lipo for it, and 2 lipos for other boat, 29"mono 540 9xl kv1898 esc 120 props not shore what to use yet x642 or m445.

is it ironic that you spell "dumb" wrong? cripes dood, i cant understand any of this

ALL single packs for the most part are 1P. S is for series. P is for parallel. Just look for packs that are 2S, 3S, 4S, etc. They are all considered 1P (another way to look at it without confusing you further is that 1P stands for 1 PACK. If you want 2P, 3P, 4P, etc., that is paralleling multiple packs.

Come on! This is NOT that difficult!

2s1p = 2cells in the pack wired in series to the connector. 2s2p = 4 cells in a pack ( 2 sets of 2 cells wired parallel) then wired in series to the connector. either way they perform the same task the same way. i dunno why some companies make 2s2p rather than 2s1p. 2s2p just means there is more room for error because there are more connections made to acheive the same result as 2s1p

I know venom makes some 3s 2p packs that have 6-cells shrink-wrapped together. Same as running 2-3s packs in paralell. Just together as one battery. I think these are more for single battery applications. Most rc boats require 2- batteries for proper weight distribution since the motor/stuffing tube sits right down the center.

Thanks for input,
Diagrams and schematics always clear things up for me !

Excellent information there as I had some questions also.

Just to be clear, if I want to double the mAh (longer run time) but keep the voltage the same I need to run two identical packs in parallel correct?

[forescott]

Yes sir!!!
