Hey everyone. I have a few lipo questions and I hope you can help.

Can anyone offer a laymans explanation of the following terms and how they apply to battery life ect... Also, how important is the 25C part of the equation?

5000 Mah

What kind of life expectancy should I get from the above battery? I expected better run times but only got about 15 minutes out of it. I was in a grass field and probably was full throttle most of the time. Stock gearing.

I have the onyx charger and I can't really discharge my batteries. Is it better to store them fully charged and then put them on again before I use them?

I was told if I buy a 3s I would need to make some kind of chasis modification. Can someone explian what is involved.

Thanks for your help.
