Running your Lipos in series or parallel?

[Tony]

Which of the following do you prefer ?

A) Series= shorter run time

B) Parallel= longer run time

[Diegoboy]

I like B. with my 2 4S packs
You should make this a Poll!

Isn't that like comparing apples and oranges?
series=shorter run time= more volts=faster speed= possible burn up
parallel= longer run time=same volts=slower speed=totally safe
BUT from what I have seen on this forum, parallel will double your C rating on lipos but I still can't grasp that. I guess you just have to assume it's true. I'm still trying to figure out if 2 10c in parallel will do the trick for my blackjack 27 and give me the minimum of 20 C. The 10c are cheaper!

I dont think you double your "C" rating. I think you double your Mah. When in parallel

[Jeff Wohlt]

nope...your c rating doubles.

correct. ie 2x 11.1v 2200mah lipos = 11.1v 4400mah

[line6]

Wouldn't it be your amp rating that doubles.

I have a BJ26 running in series. You can get Zippyflightmax 7.4v 4000mah 25C packs really cheap at HK....

AAAA for me don't care about running time it's all about speed

I have run Zippys R & Flightmax too ok batteries but don't expect too much out of them after about 35 charges the ones i have don't perform and hold charge as good as they did new

[bwells]

this should sum it up
parallel=same volt/double MaH/double C rating/slower speed but longer run time
series=double volt/same MaH/same C rating/faster speed but shorter run time
Is this exactly correct and is there anything that needs to be added or clarified besides the fact that when you double voltage you can break (as I just did)

[NorthernBoater]

parallel=same volt/double MaH/double C rating/slower speed but longer run time
series=double volt/same MaH/same C rating/faster speed but shorter run time

It should read like this.
parallel=same volt/double MaH/same C rating/slower speed but longer run time
series=double volt/same MaH/same C rating/faster speed but shorter run time

Assuming you have two packs and your choice is to either run them in series or parallel you will not be running the same motor. A motor that is meant to run on 28.8 V will be seriouslly underpowered when run on 14.4 V.

I'm thinking the C rating changes as jeff wohlt confirmed but we need a definate answer, there is no gray area here

[ozzie-crawl]

C rating is the same amps double. if the c rating doubled it would be like this
e.g 4s 20c 4000mah = 80 amps
now parallel 2 off those 4s2p 20c 8000mah =160 amps
if the c rating doubled it would meen you have 320 amps
