Need a battery guru

[hazardpro]

Hi all

I'm sure there is a calculation for working this out but my brain isn't really up to it, is there any battery guru's out there?

So....

2x 5000mAh 6s battery weighing 754g

VS

2x 6000mAh 6s battery weighing 908g

Am I going to see any flight time advantages running the 6000mAh (but slightly heavier) battery?

Only way I could attempt to work it out was like this:

5000mAh / 754g = 6.63g per mAh

6000mAh / 908g = 6.61g per mAh

advantage -0.02g per mAh if running the larger batteries (eg total 240mAh advantage)

Which would pretty much mean it was not worth it...

Thanks

Doug

Gee, I am no Guru but I very much like your calculations, seems logical and I agree with your conclusion. What do you need a guru for?

Yep sounds logical to me... However if your aircraft is reaching its maximum weight then you won't be able to do the 6A batteries... So...

I think your best at the double fives

Trying to eek a little more flight time out of our set up. 8.5mins is pretty tight.

We have a second FPV set up so ditching that may help a little, then there is the datalink which 90% of the time wont be in use, so I guess we could have that unplugged by default.

Going to weigh it all today to see what we have to play with (if anything).

More inut info is needed to answer that question, e.g., prop dia and pitch and MR+Payload weight.
Once you have all the peripheral data entered into ECalc such that you get a realistic answer to one scenario .... just make some adjustments for the 5000 versus the 6000 maH batteries and compare the results......

provides excellent insight to your question(s).
