View Full Version : Another LiPo question ...
03-24-2010, 03:04 AM
Sorry to ask another LiPo question as there are obviously many on here, of which ive read most of them and havent seen an answer to this.
An E-Revo is capable of taking 6s.
So i see most people run either 4s or 6s but from what i can gather they run either 2x 2s or 2x 3s in series?
So what i want to know is can i run 2x 4s in parallel or even 2x 5s assuming i can find some that fit ...
Basically im looking for run time, if anyone can give any info on what batteries they use and the relative run time from them that would be great.

Sorry title should say yes.... You can run two of the same voltage, capacity (mah) and c-rate lipo's in parallel for double the capacity/c rate, while keeping the same voltage.

i dont think you read that properly, i never mentioned running different packs in parallel.

Sure .... You can run two 2S in parallel, two 3S in parallel,...,two 6S in parallel. They should be similar in capacity and specs but don't need the strict matching cell rules that series configurations have.
All you need is a jumper on one series male and a parallel power adapter on the other to convert the MMM to parallel packs.

Can i just use the standard traxxas parallel connector for that or are you telling me something different, sorry im really just trying to get my head around a few things before i race in purchasing things.
Also is there a reason that most people run 2s or 3s in series rather than say 4, 5 or 6s in parallel? The only reasons i can think of with my limited knowledge is battery cost, battery size and perhaps that current run times in series are sufficient?

and the extensive dremel work that has to be done when running higher cell lipos. I haven't found any 4/5/6s cells that fit without dremel work (not saying there aren't any).

i ran a pair of 4s 20c 3700mah rhino batteries for a while. They were decent. I don't think you will be able to find any 5s or 6s batteries that will fit.
Parallel will add the capacity of the packs together. So you will ultimately be giving it double the amps of one pack as well. Series will double the voltage.

Yes sorry I originally read it wrong and thought you were asking if you could run a 2s and a 4s parallel. I then edited my post when I realized you were just asking if you can run 2 4s or 5s packs parallel. So ya like he posted you can and this thread also helped me understand you can run different mah packs parallel, I have always thought the packs had to be of equal voltage, capacity and c-rate to run parallel, so thats good to know they can be different capacity and still run safely in parallel.
