Default lipo rx pack

Hey guys just had a quick question.

I have a 2cell lipo pack in my rc8 right now and its working just fine. I use a Castle bec to lower the voltage to 6volts. But i have a 3cell lipo and was wondering if i would be able to use that as a rx pack. I could still lower the voltage down to 6volts. Would it last longer then the 2cell cause it has a higher voltage but im not using it all at once.


sorry if the way i phrased the question is a little confusing lol.

No it won't last any longer. The amount of run time depends mainly on the Mah. The more mah , the more run time. Just make sure your voltage regulator is set for a 3 cell or a 9 volt cutoff(do not take a 3cell anywhere near 6volts), or else you may discharge the battery too much and it will be shot. I'd stick with a higher mah 2 cell and be done with it, but that's just me. Good luck!

runtime depends on Watt hours the pack is able to give.

7.4V 2S 2000mah pack = 14.8Wh
11.1V 3S 1300mah pack = 14.43Wh

when used with 6V BEC they will last about the same time as from the 3S pack the BEC will take less curent

of course 3S 2000mah pack will last much longer

stick with 2S - 1500mah 7.4V pack will last for ~ 2 hours depending on servos u use. Most 2S higher capcity packs will be lighter than lower capacity 3S pack and also 3S packs will be most of the time bigger and hard to fit.
