Another Lipo question

[Helifino]

This may sound stupid,but with all of the questions regarding lipos, is there a formula for calculating what voltage and Mah rating an ESC can handle knowing the amp rating of the ESC?
Example: If I have a 5amp ESC, can I use a 1300Mah 11.1V lipo? How do you go about determining whether you could or not without frying your ESC? :confused:

HI! Yes I can see where this might be confusing. A 1300mah battery pack means that it can provide 1300 milliamps or 1.3 amps for 1 hour. This is a measure of capacity of the battery pack.

When looking at speed controllers they have a maximum Amp rating- meaning that is the maximum current that can be delivered at any moment by the Electronic Speed Controller.

So for example- if your flying a micro helicoptor like the Blade CP or Honeybee CP2 and your using a 1300 mah 11.1 volt lipo battery pack. Normal hovering current demands is about 4.5 to 6 Amps.

To determine how long your battery should last requires just a little math.

If the battery can provide 1.3 amps (1300 ma) for 1 hour
And we are flying a helicoptor that is drawing 6 amps it will last for 13 minutes.

So now your proably wondering how I go that- right?

Here is the formula:
(Capacity of the battery pack in Amp hours * the number of minutes in an hour)/ The current of your helicopter in flight

1.3 * 60/6=13 minutes
There you have it!

Good luck and happy flying!

Thank you sir for your reply and Thank you for serving our country!
I guess my confusion was in reading other replies that you could not run a certain rated lipo with a certain esc because you would burn it up. I have a 11.1v 1300Mah that I was afraid to use in my bird for that reason.
