Default Battery discharging???

Hi everybody

What's the difference bettween discharging a battery at 10A, or 20A, or 30A etc? I discharge my GP3300 down to 5.4V after every (on-road, modified) race, recharge up to 1000mAh and store the batteries until next weekend. But if I discharge at 10A, the battery will "give" much more mAh than at 20A or 30A. So when I recharge to 1000mAh, the 10A discharged battery will carry a lot less current than the 20A, or 30A. Why is this happening and what's the right thing to do?

I was told that you should discharge your packs at 20 amps for stock adn 30 amps for mod....depending on the load they take..

I've heard the theory that it's better to train the cells to discharge at a higher rate so the are more able to give up the charge quickly but I have seen no data supporting this. Some other people have also said that they think discharging at too higher rate will shorten the lifespan.

What most people do say however is that you need to decide hat you want to do and not change as the cells like the repetition. As with most things, do what works for you that isn't too much hard work that you will quit after a couple of weeks.

thanks guys, I think I'm going to stick to the 20A discharge rate, as it's not too low, or too high for the cells
