The battery in Parallel vs Series
« on: January 18, 2022, 07:49:12 AM »

If you run 2 5000mah 2s batts in parallel it's still 2s but now it's 10000mah so essentially you made your gas tank (the run time length) bigger.
If you run the same 2s batts in series it doubles the voltage so it's 4s now.
Someone correct me if I'm wrong but I don't think it works like that. Neither will increase the C rating or discharge rate of batts. 25C is maxed discharge so it doesn't make batts discharge any faster than the 25C by hooking up either way. The only thing it affects is voltage or run times, the discharge rate stays the same.

Yes I think you are right.
you either double the voltage or double the milliamps.
i assume the C rating stays the same..

If the batteries are in parallel then you can pull twice as much current from them, as you can pull max C rating from both at the same time!
If in series then the C rating is only as printed on the battery - well the manufacturers inflated C figure that's printed on the battery  ;D

As Chad said

If you run pareallel then each battery can discharge 25C each or
125A each. So with two discharge simutaniously you will have 250A on tap ( in theory as said manufacurers lie about C )
They don't discharge any faster, but you have twice the capacity so twice as much to discharge in the first place

Reminds me of an experiment I did with my old TBS Discovery and two old 2200mAh lipos that were past their best...

Using each battery individually, if I throttled up the quad the voltage dipped dramatically and the flight time was next to nothing.

If I put them in parallel and used both at the same time, the voltage drop was minimised because they shared the current demand between the batteries (so in effect the drain was halved). I was able to use said batteries together for a while instead of binning them.
