Lipo advantages?

[Scott711]

I'll be using 9920/8XL combo on my supermaxx. Ideally I would like to use just one pack. I'm sure there are many packs to look at but I'm looking at the one below. It may be a little much for the 9920. Does the 99 amp rating on the esc refer to a cotinuous draw or a peak that it can sustain? Sorry to be so thick headed on this stuff but I'm still going through the learning curve on this lipo stuff. Thanks.
