nerdnic | Lipo Battery mAh vs C Rating (Turnigy Graphene and Zippy Compact)

[@gooniac33]

Thanks for posting this one!! I am one to go more for higher capacity and lower C. It usually helps with weight and the discharge rate is actually better it real world testing. By that I mean in flight and not on the bench. I rarely go above 30c as a result. I do half throttle tests since that is where most of my time is spent with some full throttle bursts mixed in there. That is how I fly...

Thanks for looking at this comparison! Did you pick the 1300mAh battery simply because you had it handy? (understandable) Or was it chosen for its similar physical size and mass? On a purely math-curious basis....I'm curious about how a "mAh vs C" shootout would turn out if the "high mAh/low mAh" and "high C/lowC" ratios were more equal. What I mean is; 65C vs 40C is a 62.5% advantage in output for the High-C battery, but 1300 vs 1000 mAh is only a 30% increase for the lower-C battery. How would the results turn out if you compared a similarly-ratio'd pair of batteries? For example: 1000mAh-65C vs. 1625mAh-40C .... 65/40=1.625, 1625/1000=1.625 (or at least something closer, like a 1600mAh)

The 1300 was chosen for both reasons, I had it on hand and it was very close in size/weight. I can definitely do another comparison as you're suggesting. However, I'd expect the larger mass battery to perform better, so in this case the 1625. Having both batteries basically be the same size/weight is an important feature because it's realistic to be limited on which battery size works with your rig, and it demonstrates comparable power density.

[@TheHarberHangar]

Absolutely agree; the size/mass similarity is an important feature when assessing how much energy you can put in a given space/location. I was coming more from the pure numbers side of things, framing the question such as; "regardless of mass or dimensions, does X% increase in C-rating still beat the same X% increase in mAh-capacity?" While some may be concerned with maintaining the same mass in their rig, high-C batteries are quite a bit more expensive than lower-C-higher-mAh ones. We can't all pony up for Graphene in our planes. ;) That said, if cost is not a barrier and speed is your ultimate goal, high-C batteries are the way to go. :)

Like your common sense way of presenting these facts.

[@kdobson83]

Have you heard of the Titan lithium ion batteries? I would love to see a comparison of those to some normal lipos. There's a guy on KZbin who raves about them and their longer flight times. Like DOUBLE what a lipo can do. I saw one video where a guy flew a Bixler for an hour straight on one Titan battery. Is this possible? How? And if so, why are these batteries not more popular? Do these hold up in high consumption scenarios? 👍

[@nerdnic]

I've not tested them before. From my understanding they have a really low discharge rate (low C) so while they pack a lot of mah, they don't have the brute power of a lipo.

[@mohittomar920]

Sir i have a query The battery with 60c will drain faster than 35c or not??

[@nerdnic]

Yes it will. The energy is transferred faster in the higher C battery.

Thank you for the video I want to buy a battery for 1/10 and for 1/8 rc car Battery 7000mah 25c There is battery 5000mah c70 11.11v what is impotant to me time to play No power What to choose

[@nerdnic]

Hafez Muhtaseb if the 7000mah will fit in your car, get that one.

[@hafezmuhtaseb6711]

Nic LechnerI apologize because my English is not excellent and I am a beginner in the world of rc but does c have any relation to the heat and the duration of use and thanks for the answer

[@hafezmuhtaseb6711]

oun dhk jlb and vkar rc car

[@nerdnic]

Hafez Muhtaseb A higher C battery will not get as hot. But motor temperature is not connected to C rating.

Thank you for help
