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.
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.

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.
Maybe this will help you understand. http://www.offshoreelectrics.com/lipo.php

Thanks for input,
Diagrams and schematics always clear things up for me !
HAPPY HOLIDAYS AND ALL THE BEST WISHES !

Yes sir!!!
Do the batteries running in parallel need to be exactly the same? For example can one be a 5000 mAh 6s 40C and the other be the same but a 30C?
Or maybe a 4000 mAh 6s 40C in parallel with a 5000 6s 40C?
Ideally it would be best to keep them the same because the amp ratings will be different on each pack. It will probably work, but if run down too low I'm not sure how the lvc on your speed control would see it and you might ruin the smaller pack. Lipos can be dangerous if not used correctly and if it were me I wouldn't chance it with that nice build and all that $$$ worth of components. JMO!
Gotcha, that makes sense about the LVC on the ESC. Damn......HK is out of the 5000 mAh 6s 40C Turnigy packs. I should have bought 4 from the get go instead of just 2.
Do not mix packs! Stay with identical, including from the same manufacturer. You're asking for trouble otherwise.

Anyplace else I can get Turnigy packs besides HK? The packs I need are back ordered.
That was some explanation about the difference between the 2s 1p and 2s 2p that even a “dumbo” like me could understand what all that was about!! I am sure that must helped a lot of people to really make up their builds about how they want to go about building their boats!!
