I agree, i know no lipo is rated for close to that many amps 850... but I want an accurate guesstimate at least of the power being used under full load. I dont want to see a single cell ever begin to puff on my ~$170 4s. Knowing the power load will greatly help to assess proper gearing range without too much strain on battery.
