Default Can a 11.1V 1300mAH battery be used instead of 1250mAH battery?

So I'm looking at an EDF jet with a 370 brushed motor and it says it requires an 11.1V, 640 to 1250mAh LiPo battery.

I have a 11.1V, 1300mAh lipo and was wondering if I could use that or if it was a bad idea with that extra 50mAh.

It is virtually the same battery. Ganted the same company, same cells, same discharge rating. But anyways, if it can handle the load it will be no problem.

Absolutely! The mah rating has nothing to do with anything other than flight times. The higher the mah rating, the longer you can fly. 50mah isn't even gonna be noticeable though. Keep in mind though, that the only real difference is size and weight. But that is only an issue with two batteries with a larger mah difference.

For example, a 3s 11.1v 1200mah Li-po and a 3s 11.1v 2200mah Li-po. Naturally the 2200mah battery is going to be larger and weigh more. You are more than safe to use your 1300mah Li-po friend.

What's the "C" rating for the recommended battery and the "C" rating for the battery you plan on using? I ask because the higher the rating the more "juice" it can dump into your application to the motor. If you have a lower "C" rating than what's recommended, you could kill your battery, and that's not good with a Li-po. It could make it puff up and then it would be no good. Don't mean to scare you friend, but just double check the specs of the recommended battery first. Good winds bud.

Great info guys. What does "C" rating stand for? I still have much to learn.

The "C" is in reference to current. The higher the "C" rating on your battery, then the faster it can discharge. All my batteries have a minimum of 20C. Now this is just my personal preference. Not only does it give me peace of mind, but I also don't have to worry about using them in multiple applications that may be different from on another. For example, if I have a 3s 11.1v 1200mah 10C Li-po that I use for a smaller motor, then I couldn't use it for a plane with a bigger motor because the motor would pull from my battery quicker than it can discharge, causing it to puff up and die. NOW, if I'm using the same Li-po as described, but with a 20C rating, I can use them in either plane for either motor. You can never have "C" rating too high, but you CAN have a "C" rating too small. I hope this helps.

If we're lucky, we'll get Firemanbill in here soon. He's great at explaining all this.

It is very simple. C*Ah=Constant discharge rating.

20C*1800mAh(1.8Ah)=36 Amps
