Just got my new SMC 4600 70c batteries. I want to make them last, so does SMC require and pre-charging steps? Or should I just charge it and run it and it will be fine?

Also, to make sure...charging these batteries at anything over 1c doesn't increase the overall performance, and the only benefit is a faster charge, correct?

What I would do with these packs, since I have a 50w charger is charge at 4.6a on 2 cell and run them. I usually don't store my batteries, but I race weekly. Partially because I don't hear of many people storing them, and I don't know how to or what to store them at because everyone says different.

Any feedback and tips would be greatly appreciated!
